Answer:
A. 25°
Step-by-step explanation:
We are given a circle and two intersecting lines of circle meets at s and form an angle 34° at S.
Also, we have W and X points on circle that form a minor arc and T and R makes a major arc of angle 93°.
In order to find the value of minor arc WX, we need to apply following formula:
Subtends angle on intersection of lines =
Plugging values in above formula, we get
34=
On cross multiplication, we get
34 × 2 = 93-x
68 = 93 -x
x = 93-68
x= 25.
<h2>Therefore, measure of arc WX = 25°.</h2><u />

Answer:
Total surface area of the prism = 920 cm²
Step-by-step explanation:
Given prism has 2 similar triangular surfaces and 3 rectangular surfaces of different dimensions.
Area of one triangular side =
Area of 2 similar sides = Base × Height
= 8 × 15
= 120 cm²
Area of rectangular side with dimensions 17cm × 20cm
Area of the side = 17 × 20 = 340 cm²
Area of the second rectangular side with dimensions 8cm × 20cm
Area of the side = 8 × 20 = 160 cm²
Area of third rectangular side with dimensions 20cm × 15cm
Area of the side = 20 × 15 = 300 cm²
Total surface area of the given triangular prism = 120 + 340 + 160 + 300
= 920 cm²
