Answer:
x=22
Step-by-step explanation:
4x+2+x+3x+2=180
collect like terms
4x+x+3x=180-(2+2)
8x=180-4
8x=176
make x the subject of the formula
x=176/8
x=22
Answer:
98.
Step-by-step explanation:
You have to do it in order so you can get the correct answer. Do the problem in the parenthesis first. 6 ÷ 3 = 2.
It should look like this:

TSA of ice cream cone = 330 cm^2
Step-by-step explanation:
Total Surface Area of ice cream cone = pie r( r+h )
22/7 * 7 (7+8)
22 ( 7+8)
22*15
= 330 cm. square
∠M=90°-23.1°=66.9° - it's a right answer.
u=d/sin∠D=97.25
m=cos∠D*u=89.52
