<h2><u><em>36x squared - 16y squared </em></u></h2>
You must multiply 5x-3 with 5, then you will get
25x-15 = 1
25x = 1+15
25x = 16
x = 0.64
Answer:
70°
Step-by-step explanation:
∠A =112°,
Exterior angle to angle B is 2x, therefore ∠B = 180 -2x (angle on straight line)
Exterior angle to angle C is 2x + 12, therefore ∠C = 180 -(2x +12) (angle on straight line) = 180 - 12 -2x = 168 - 2x
∠A + ∠B + ∠C = 180 (sum o angles in a triangle)
112 + 180 - 2x + 168 - 2x = 180
460 - 4x = 180
4x = 460 - 180 = 280
x = 280/4 = 70
x = 70°
Answer:
12
Step-by-step explanation:
We just plug in 8 for x and 3 for y which gives us 1/2 * 8 * 3 = 12.
