I graphed the inequality on the graph below and found which answer was a solution.
If this answer is correct, please make me Brainliest!
Point B of the Triangle = ( x+2)
Point C of the Triangle = ( 6x+10)
(a) What is the value of x? Show your work.
(b) What is the measure of angle C? Show your work.
The 3 inside angles of a triangle need to equal 180 degrees.
Add the 3 angles together to equal 180:
X + x+2 + 6x +10 = 180
Simplify:
8x + 12 = 180
Subtract 12 from each side:
8x = 168
Divide each side by 8:
x = 168 / 8
X = 21
a) x = 21
b) C = 6x+10
replace x with 21:
6(21) + 10 =
126 +10 = 136
Answer:
x = 21 and C = 136°.
Step-by-step explanation:
(a) Sum of all the triangle = 180°.
∠A + ∠B + ∠C = 180°.
∠A= X, ∠B = x +2 , ∠C = 6x+10.
X + x + 2 + 6x + 10 = 180°.
8x + 12 = 180°.
8x = 168.
x = 21.
(b) The measure of angle C can be done by substituting the vale of x = 21.
6x + 10, x= 21.
=6 × 21 + 10
=136°.
Thus, the value of x = 21 and C = 136°.
B) 4 and 5
C) 6 and 7
D) 7 and 8
The third angle is 80 degrees
x + 2y = 1
