In triangle ABC, M< A = 90° And M< C = 22° what is the measure of angle B

dedylja [7]

Answer:

The answer for ∠B = 68°

Step-by-step explanation:

Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :

∠A + ∠B + ∠C = 180°

90° + ∠B + 22° = 180°

∠B = 180° - 90° - 22°

= 68°

20 POINTS!!!! If eight is added to twice a number and the sum is multiplied by five result is the same as if the number is multi

Sauron [17]

<h3>The value of x is equal to -2.</h3>

5(2x + 8) = -8x + 4

Distributive property.

10x + 40 = -8x + 4

Add 8x to both sides.

18x + 40 = 4

Subtract 40 from both sides.

18x = -36

Divide both sides by 18

x = -2
