Answer:
x = -4, y = 8
Step-by-step explanation:
y - 12 + 2y = 12
=> 3y = 24
=> y = 8
x = 8 - 12
=> x = -4
Answer:
96
Step-by-step explanation:
Divide 64 by 2
add 32+ 64
x=96
We are given

we know that

so, we get
opposite =7
adjacent=24
now, we can find hypotenuse


now, we can draw triangle and then switch vertices accordingly
we can find cos(B) using second triangle

In second triangle:
adjacent=7
hypotenuse =25
so, we get
