Answer:
11 is correct
12 should be 51°
Step-by-step explanation:
15/sin(104) = 12/sin(J)
J = 50.917°
Answer:
20
Step-by-step explanation:
f(x) = 30
30 = 1.8x -5.4
35.4 = 1.8x
x = 35.4/1.8
x = 19.666
Answer:
Step-by-step explanation:
The surface area of the square pyramid is: 451 cm²
The lateral surface area of the square pyramid = 330 cm²
<h3>What is the Lateral Surface Area and Surface Area of a Square Pyramid?</h3>
Surface area = a² + 2al, where a is the base edge and l is the slant height.
Lateral Surface Area = 2al.
Given the following:
Surface area = a² + 2al = 11² + 2(11)(15)
Surface area = 451 cm²
Lateral Surface Area = 2al = 2(11)(15)
Lateral Surface Area = 330 cm²

Answer:
66.67%
Step-by-step explanation:
We know that a foot is equal to 12 inches.
First, we write it in the form of a fraction.
8 inches of a foot = 8/12
Then we simplify the fraction.
8/12 = 2/3
After that, to write the number in percentage form, we need to multiply the fraction by 100%.
2/3 x 100% = 66.67% (Nearest hundredth)
