the ratio of the measures of three angles in a triangle is 10:3:7 find the measure of the largest angle
1 answer:
Answer:
90°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the parts of the ratio 10 + 3 + 7 = 20
divide 180 by 20 to find the value of one part of the ratio
= 9° ← 1 part of the ratio
the largest angle is the one with 10 parts of the ratio, hence
10 parts = 10 × 9° = 90° ← largest angle

Hi there!
f(x) = -2x - 3
Plug in 0 for "x" to solve for f(0):
f(0) = -2(0) - 3
f(0) = -3
Since the question is asking you to evaluate f(0) - 7, simply subtract:
-3 - 7 = -10.
