In quadrilateral ABCD m < A= 90°
m 2 C = 50° and m < B = m D.
Find the degree measure of < B.

In Quadrilateral ABCD M &lt; A= 90m 2 C = 50 And M &lt; B = M D.Find The Degree Measure Of &lt; B.

Answers

Answer 1

Answer:

m∠B = 170°

Step-by-step explanation:

Sum of all angles in quadrilateral is 360°:

m∠A + m∠B + m∠C + m∠D = 360°

m∠B = 360° - m∠A - m∠C - m∠D

m∠A = 90°

m∠B = m∠D= 50°

m∠B =  360° - 90° - 50° - 50° = 170°

[tex]\huge\boxed{\text{E. } \frac{1}{2} }[/tex]

Step-by-step explanation:

When finding the cosine of an angle, we need to note what each terms mean.

Using the acronym SOH CAH TOA, we know that the

Cosine of an angle will be it's

Adjacent side divided by the

Hypotenuse.

The side adjacent to the 60° angle is 1, and the hypotenuse of the triangle is 2. Therefore, the adjacent over the hypotenuse is [tex]\frac{1}{2}[/tex], making the cos of 60°

[tex]\frac{1}{2}[/tex].

Answers

Answer:

1.2 years

Step-by-step explanation:

The value of a certain account after t years is given by :

B = 600 × 1.2t dollars ....(1)

We need to find how long will it take for the value of the account to increase to $900 i.e. we need to find the value of t.

Put B = $900 in equation (1).

[tex]900=600\times 1.2t\\\\t=\dfrac{900}{600\times 1.2}\\\\t=1.2\ \text{years }[/tex]

So, it will take 1.2 years of the account to increase to $900.

Answers

Answer:

y = -2x - 8

Step-by-step explanation:

Slope-intercept form is y = mx + b. Slope is m, and y-intercept is b. To do this, we substitute -2 for m and -8 for b. When we do this, we get y = -2x + -8. We can simplify this to y = -2x - 8.

Answers

Answer:

Step-by-step explanation:

427,963

If the number behind what number you're trying to round is greater than 4 then the number you're rounding goes up once while everything behind it goes to zero. If it's below 5 than the it well stay the same. Ex. Round nearest tenth--> 14--->10  instead of it going up to 20 it stays 10.

427,963

      ^

This number is higher than 4 so the number in front or the thousand mark goes up a number.
