Answer:
correct answer: 120,000 cm!
Answer:
C. 21
Step-by-step explanation:
To find the answer, we can use the angles sum of triangle, where the sum of angle of a triangle will be 180°.
In this case, we can set an equation to find the answer:
35°+52°+3(x+2) = 180°
3x + 3(2) = 180°-35°-52°
3x = 95 - 6
x = 87/3
x = 29
Therefore, x = 29.
We can then find the measure of angle C by putting the value x in the equaiton:
3((29)+2)
=29(3) + 2(3)
=87 + 6
= 93°
Therefore, angle C is 93°.

Answers:
x = -3
base angle = 49 degrees
============================================
Work Shown:
The missing angle is (2x+55) degrees since the base angles are congruent.
Add up the three angles and set the sum equal to 180. Solve for x.
(82)+(2x+55)+(2x+55) = 180
4x+192 = 180
4x = 180-192
4x = -12
x = -12/4
x = -3
Use this x value to find the base angle
B = base angle
B = 2x+55
B = 2*(-3)+55
B = -6+55
B = 49 degrees
Answer:
d
Step-by-step explanation:
Slope intercept form: y = mx + b
y = -x + 7
x + y = 21
x + y = 21
-x -x
y = -x + 21
y = -x + 7
y = -x + 21
Parallel lines have the same slope. Here, our slope is -1
Therefore, our final answer is d.
