Answer is C.
Since each side is 68/4 = 17 cm ( the hypotenuse of each right triangle), and half of the shorter diag is 8, then 17^2-8^2 = a^2
225=a^2
15 = a, which is half of the larger dish, so the larger diag is 30cm.
Answer:
x = 23
Step-by-step explanation:
Add 20 to both sides of the equation
x-20=3
−20+20=3+20
Simplify
Solution:
x= 23
Answer:
40°, 60° and 80°
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.
180° ÷ 9 = 20° ← value of 1 part of the ratio , then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The angles in the triangle are 40°, 60°, 80°
