Answer:

c = 12.5

Step-by-step explanation:

a² + b² = c²

10 and 7.5 are bases of the triangle, that means they stand for a and b

the equation would be

10² + 7.5² = c²

square the numbers

100 + 56.25 = c²

156.25 = c²

√156.25 = √c²

12.5 = c

What is the value of c to the nearest degree
iren [92.7K]
Tangent is the ratio opposite/adjacent

tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer

The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
