Pythagorean theorem: A^2 + B^2 = C^2

C is the hypotenuse, the side opposite from the 90 degree angle. So we have C and A.

c^2 - a^2 = b^2

23^2 - 16^2 = b^2

b^2 = 273

b= 16.5

Answers

Answer:

BCD = 90˚

ABD = 16˚

CBE = 74˚

ADE = 74˚

AEB = 148˚

DEA = 32˚

Step-by-step explanation:

BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.

ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).

CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.

ADE: Same this as CBE for same reason.

AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).

DEA: Subtract AEB from 180˚ because they’re supplementary angles.

When adding integers with the same sign, add the absolute values of the integers.
True or False?

Answers

Answer:

False. This only goes with integers that are both positive.

Step-by-step explanation:

For example, 7+6 is the same as |7|+|6|, which is, again, the same as 7+6.

However, when you add integers that are both negative, you're subtracting, and you'll always end up with a negative difference. Absolute values are always positive, which is why this doesn't work.

(-7)+(-6)

= -7-6

= -13

|-7|+|-6|

= 7+6

= 13

Find the measure of each missing angle. ​Subject: Geometry
Unit 5: Relationships in Triangles
Homework 1: Triangle Midsegments

Answers

Answer:

Q10

∠1 = ∠5 = 180° - 144° = 36°∠2 = 56°∠3 = 180° - 56° = 124°∠4 = 144° - 56° = 88°∠5 = ∠1 = 36°

Q11

∠1 = 35°∠2 = 180° - 35° = 145°∠3 = 90° - 35° = 55°∠4 = 180° - ∠5 = 180° - ∠3 = 180° - 55° = 125°∠5 = ∠3 = 55°

Measure of angles for figure 1:

∠1=36∠2=56∠3=124∠4=88∠5=36

Measure of angles for figure 2:

∠1=35∠2=145∠3=55∠4=125∠5=55

The angle is formed by two rays at a common point of the two rays.

For given figure 1:

∠1+144=180 (Sum of angles on same side of transversal is 180°)

∠1=180-144

∠1=36

∠5+144=180(Sum of angles on a line is 180°)

∠5=180-144

∠5=36

Similarly, ∠3=180-56

∠3=124

∠4+36+56=180(Sum of all angles of a triangle is 180°)

∠4=180-36-56

∠4=88

∠2+36+88=180

∠2=56

Thus, measure of angles for figure 1 are ∠1=36, ∠2=56, ∠3=124, ∠4=88, ∠5=36.

For given, figure 2:

∠1=35(Alternate angle on same side of transversal are equal)

∠2=180-35

∠5=180-35-90(Sum of all angles of a triangle is 180°)

∠5=55

∠4+55=180(Sum of angles on a line is 180°)

∠4=180-55

∠4=125

Similarly, ∠2=180-35(Sum of angles on a line is 180°)

∠2=145

∠3=180-35-90(Sum of all angles of a triangle is 180°)

∠3=55

Thus, measure of angles for figure 2 are ∠1=35, ∠2=145, ∠3=55, ∠4=125, ∠5=55

Apply to the given triangle

Side FE

FE / DE = sin 38° (or cos 52°, the value is same)FE / 18 = sin 38°FE = 18 sin 38°FE = 11.08

During the months of August and September the total rainfall I August was 0.6 inch more than the amount f rainfall in September, how much rain fell in each month?

Answers

Answer:

August = 3.4

September = 2.8

Step-by-step explanation:

Given

[tex]Total = 6.2\ in[/tex]

Represent August with A and September with S.

So,

[tex]A =S + 0.6[/tex]

Required

Amount of rainfall in each month.

This is calculated using:

[tex]Total = August + September[/tex]

[tex]6.2= A + S[/tex]

Recall that: A = S + 0.6. Substitute

[tex]6.2= S + 0.6 + S[/tex]

[tex]6.2= 2S + 0.6[/tex]

Collect Like Terms

[tex]2S = 6.2 - 0.6[/tex]

[tex]2S =5.6[/tex]

Solve for S

[tex]S = 5.6/2[/tex]

[tex]S = 2.8[/tex]

Substitute 2.8 for S in [tex]A =S + 0.6[/tex]

[tex]A = 2.8 + 0.6[/tex]

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

7 times the sum of y and 1/3

This can be written as,

= 7 (y + 1/3)

=7 (3y + 1) / 3

= 7/3 (3y + 1)

Answer:

JKLM ~ QRSP, scale factor 0.6ΔABC ~ ΔUVT, scale factor 1.5

Step-by-step explanation:

We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.

1. JKLM ~ QRSP

  JK : KL : LM : MJ = 20 : 15 : 24 : 25

  QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)

The scale factor is 12/20 = 0.6.

__

2. ΔABC ~ ΔUVT

  AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6

  UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)

The scale factor is 24/16 = 1.5.
