Answer:
3:4, 3/4, and 3 to 4
Step-by-step explanation:
It's correct
<span>Given ratio between the base angle and vertical angle of an isosceles traingle is 2:5
⇒ base angle / vertical angle = 2 / 5
let base angle = x
⇒ verticle angle = (5/2)x
we know that
verticle angle + base angle + base angle = 180°
⇒ ( 5/2 + 1 + 1 ) x = 180°
⇒ (9/2)x = 180°
⇒ x = ( 180° x 2) / 9
⇒ x = 40°
verticle angle = (5/2) x 40° = 100°

Answer:3.9
Step-by-step explanation:
you have to add the decimal to the exponent
The answer is D because
60 times 5=300
20 times 8=160
25 times 9=225
33 times 10=330
Then add all of them and it gives you $1,015
