Answer:
15x-2+7x+4=90°[being complementary angle]
22x+2=90°
22x=90°-2
22x=88
x=88/22
x=4

Answer:
Step-by-step explanation:
To calculate the lateral surface of this shape we must divide it into 3 parts :
- Part 1 : the half cylinder with the radius r=15
We must calculate its perimeter P1 :
P1 = (15*2)*π/2 = 30*π*(1/2)=15π
- Part 2 : the half cylinder with the radius r=12-5=7
We must calculate its perimeter P2:
P2= (7*2)*π/2=14*π*(1/2)= 7π
We won't calculate its perimeter because it has some common sides with the cylinders .
Let P3 be the perimeter of what's remaining from the cube
P3=12+5= 17
Now the total perimeter : Pt
Pt= 15π+7π+17= 22π+17
The lateral surface : Ls
Ls= (22π+29)*8= 784.92 m²
