The measure of angle C (m ∠C) is 40°
<h3>Calculating angles in a triangle </h3>
From the question, we are to determine the measure of angle C (m ∠C)
In any given triangle, the sum of all the angles is 180°
Thus,
In ΔABC, the angles sum up to 180°
That is,
∠A + ∠B + ∠C = 180°
From the given information,
m ∠A = 80°, m ∠B = 60°
Thus,
80° + 60° + m ∠C = 180°
140° + m ∠C = 180°
m ∠C = 180° - 140°
m ∠C = 40°
Hence, the measure of angle C (m ∠C) is 40°

Answer:
8-(-2)
minus,minus means magiging plus so,
8+2=10
Step-by-step explanation:
Mark me please
The second one because domain refers to x, and since at (-3,-4) the point is hollow, the sign should be < without the line under it
Answer:
r= 5/4
Step-by-step explanation:
3/2= 12/8
subtraction property of Equality
-2/8 from both sides
r= 10/8
simplify
r=5/4
Multiply the parentheses by 4
10+4x+4+5
^calculate the sum of the positive numbers
