Answer:
Solve
Step-by-step explanation:
To find the surface area of a triangular prism, use the formula Surface Area = L + 2B, where L is the lateral area and B is the area of the base. Find the lateral area by calculating the perimeter of the base and multiply it by the height of the prism.
Answer:
15 ÷ 17
Step-by-step explanation:
Since our hypotenuse side is 17 cm, our opposite side is 8 cm and our adjacent side is 15 cm. Since the acute angle is x degrees,
From trigonometric ratios, cosx° = adjacent/hypotenuse
= 15 cm/17 cm
= 15/17
= 15 ÷ 17
180-65=115
115-42=73
i think the answer is 73°
Answer: x = 19; y = 98
because 2 lines are parallel
=> y - 28 + 110 = 180
5x + 15 = 110
<=> y = 180 - 110 + 28
x = (110 - 15)/5
<=> y = 98
x = 19
