Tan A = opposite side / adjacent side = 15/8
D. X = 10
6x-20= 40
6x=40+20
6x=60
X=10
4x-y=5 Would be the y-intercept (0,7) 2x+y=7 Would be the x-intercept (3.5,0)
Sorry if wrong
Answer:
Yes
Step-by-step explanation:
A right triangle's formula, according to Pythagorean's Theorem, is a² + b² = c². a and b are the two legs, and c is the hypotenuse. To solve, we must substitute the variables with the given measurements.
9² + 12² = 15²
Let's now solve:
81 + 144 = 225
225 = 225
The formula works out in the end, so it is a right triangle!
