<u>By supplementary angle property</u>,
x + 78° = 180°
x = 180° - 78°
<u>x = 102°.</u>
Answer:
The answer is 30
Step-by-step explanation:
You have to do 5 times 2. 5 times 2 is 10. Then you have to do 10 times 3. 10 times 3 is 30. So you will get 30 as your answer.
3 + 2 = 5
<span>80p / 5 = 16p </span>
<span>1st part = 2(16p) = 32p </span>
<span>2nd part = 3(16p) = 48p </span>
<span>48p : 32p :: 3 : 2 </span>
Answer:
659.4 cm^2
Step-by-step explanation:
The area of the curved surface of the cone = πrL
= π*7*16
= 3.14 * 112
= 351.68 cm^2,
Surface area of the hemisphere = 2 π r^2
= 2*3.14*7^2
= 307.72 cm^2.
Total area = 351.68 + 307.72
= 659.4 cm^2.
The answer is going to be 17%. hope that helped
