Answer:
AB = 19.05
∠A = 45°
∠C = 45°
Step-by-step explanation:
To find a missing side length, Use Pythagorean Theorem
Pythagorean Theorem: [tex]a^{2} +b^2=c^2[/tex]
Then fill in the dimensions given in the triangle
In this case, we're looking for b^2 so...
[tex]11^2+b^2=22^2[/tex]
[tex]121+b^2=484[/tex]
[tex]b^2=484-121[/tex]
b^2 = 363
[tex]\sqrt{363} =19.05[/tex]
so the answer is approximately 19
Now in this case we already know the measure of B by the 90° angle.
so if the total is 180, then 180 - 90 = 90 then divided by 2 for the 2 missing angles = 45°
so the answer is 45°
Answer:
AB=11SR3 or about 19.1. Angle A is 30 degrees. Angle C is 60 degrees. SR(square root).

2. Find the base of a triangle which has an area of 2 1/4 square inches, and a height of 1/8 in.
Answer:
36 inches
Step-by-step explanation:
Given data
Area of triangle =2 1/4 square inches
Area =9/4 square inches
Height of triangle =1/8 inches
We know that the expression for the area of triangle is
Area = 1/2Base *Height
9/4=1/2*Base *1/8
9/4=Base/16
Cross multiply
16*9=Base*4
144=Base*4
Base =144/4
Base=36 inches

A) Add 3 blocks to the right side
B) Add 4 blocks to the right side
C) Take away 3 blocks to the left side
D) Take away 5 blocks to the left side
Answer:
D
Step-by-step explanation:
Answer:
D) Take away 5 blocks to the left side is once again the correct option.
Step-by-step explanation:
we need to have the same amount of blocks on each side to make it balanced.
There are 8 blocks on the left and 3 blocks on the right.
Option A) 8 = 6 is not balanced.
(8 = 3 + 3)❌
Option B) 8 = 7 is not balanced.
(8 = 3 + 4)❌
Option C) 5 = 3 is not balanced.
(8 - 3 = 3) ❌
Option D) 3 = 3 is balanced!
( 8 - 5 = 3)✅

Find the largest interior angle of the
triangle given the information below.
C bears 056° from D.
F bears 115° from D
F bears 184° from C.
Answer:
The largest interior angle of ΔCDF is ∠F
Step-by-step explanation:
The bearings of the vertices of the triangle are given as follows;
The bearing of C from D = 056°
The bearing of F from D = 115°
The bearing of F from C = 184°
By angle addition property, we have;
The bearing of F from D = The bearing of C from D + ∠D
∴ ∠D = The bearing of F from D - The bearing of C from D
By plugging in the values, we have;
∠D = 115° - 056° = 59°
∠D in triangle ΔCDF = 59°
∠D = 59°
By alternate interior angles, we have;
The bearing of C from D = 056° = ∠BCD
Also, we have;
The bearing of F from C = ∠BCF + ∠ACB
∠ACB = 180°
∴ ∠BCF = The bearing of F from C - ∠ACB
∠BCF = 184 - 180° = 4°
∠C in ΔCDF = ∠BCD - ∠BCF
∴ ∠C = 056° - 4° = 52°
∠C = 52°
From angle sum property of ΔCDF, we have; ∠F = 180° - ∠C - ∠D
Therefore; ∠F = 180° - 52° - 59° = 69°
We have; ∠C = 52°, ∠D = 59°, ∠F = 69°, therefore;
∠F in triangle ΔCDF, has the largest interior angle.

Which of the following theorems verifies that XYZ - UWV
Answer:
I think it's AA because the sum of a triangle is 180 and if you subtract the right angle and the other angle from 180 it gives you the same angle in the other triangle.
Step-by-step explanation:
180-(90+70)=20 The other angle in the first triangle
180-(90+20)=70 The other angle in the second triangle
These angles show that they're similar

2021 Illuminate Education Inc
Answer:
A
Step-by-step explanation:
The number of texts per day by students in a class is normally distributed with a
mean of 130 texts and a standard deviation of 20 texts. Identify all true statements.
1. A little more than 2% of the students text
under 90 times per day.
2. About 50% of the students text more than 130 times per day.
3. About 15% of the students send over 190 texts per day.
4. About 68% of the students text between 100 and 130 times.
5. A student texting 130 times per day would have a z score of 1.
6. A student texting 160 times falls between 1 and 2 standard deviations from the mean.
Answer:
1, 2, 6
Step-by-step explanation:
The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]
Given that mean (μ) = 130 texts, standard deviation (σ) = 20 texts
1) For x < 90:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{90-130}{20} =-2[/tex]
From the normal distribution table, P(x < 90) = P(z < -2) = 0.0228 = 2.28%
Option 1 is correct
2) For x > 130:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]
From the normal distribution table, P(x > 130) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 50%
Option 2 is correct
3) For x > 190:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{190-130}{20} =3[/tex]
From the normal distribution table, P(x > 3) = P(z > 3) = 1 - P(z < 3) = 1 - 0.9987 = 0.0013 = 0.13%
Option 3 is incorrect
4) For x < 130:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]
For x > 100:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{100-130}{20} =-1.5[/tex]
From the normal table, P(100 < x < 130) = P(-1.5 < z < 0) = P(z < 0) - P(z < 1.5) = 0.5 - 0.0668 = 0.9332 = 93.32%
Option 4 is incorrect
5) For x = 130:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{130-130}{20} =0[/tex]
Option 5 is incorrect
6) For x = 130:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{160-130}{20} =1.5[/tex]
Since 1.5 is between 1 and 2, option 6 is correct
