Answer:
114.24°
Step-by-step explanation:
7(15)+6= 105
3(15)= 45, now we plug it in the formula, 

so now we square root it
= 114.24
X - y/2 = 4
x - 4 = y/2
2(x - 4) = y
2x - 8 = y.....so we sub in 2x - 8 in for y in the other equation
3x - 2y = 11
3x - 2(2x - 8) = 11
3x - 4x + 16 = 11
-x = 11 - 16
-x = -5
x = 5
2x - 8 = y
2(5) - 8 = y
10 - 8 = y
2 = y
It has one solution and it is (5,2)
Answer:
Step-by-step explanation:
That is the area of a trapezoid
A=h(b1+b2)/2
We are given everything but the height so
h=(2A)/(b1+b2), now using the values given to us we have
h=(2(15))/(2+3)
h=30/5
h=6
