Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2
1024 = a^2 find the root for both sides
32 = a
Vertex form is y = -(x+4)^2+9
Answer:
162°
Step-by-step explanation:
To convert from radian to degree measure
degree measure = radian measure × 
, then
degree = 
× ( cancel π and 10/ 180 to simplify )
= 9 × 18
= 162°
Answer:
7500
Step-by-step explanation:
1 year= 2500
3 years= x
So we got
2500 × 3 = 7500
