Answer:
m∠C = 60°
Step-by-step explanation:
First, let's start with the fact that all angles in a triangle add up to 180°. That means that:
x+3x+2x=180°
We can simplify it into:
6x=180°
To figure out x, we need to divide 180 by 6.
That means each x is 30°
m∠C = 2x
m∠C = 60°
Answer:B=17-R
Step-by-step explanation:
I am not sure how to simplify this equation further. We know that B+R= 17 (pens) ---- so--- 17-R=B
Answer:
11. B.
12. C.
13. A.
14. D.
Step-by-step explanation:
for 11: we know that angles D and J are congruent from the tick marks, we also know that ∠FKD and ∠LKJ are congruent (vertical angles are congruent) therefore we need the sides between them
for 12: we know that ∠STU and ∠TUG are congruent, we also know that line TU is congruent to TU (reflexive property), therefore we need the angles adjacent to the first angles listed.
for 13: we know that ∠PQR and ∠CQR are congruent, we also know that lines RQ and RQ are congruent (reflexive property), therefore we need the other angles to which line RQ is between.
for 14: we know ∠B is congruent to ∠T and line AB is congruent to line ZY. therefore the angle cannot be connected to lines AB and ZY.
