Answer:
∠2 = 18°
Step-by-step explanation:
∠WXZ = ∠1 + ∠2 ← substitute ∠1 = 3∠2
∠WXZ = 3∠2 + ∠2, that is
72 = 4∠2 ( divide both sides by 4 )
18 = ∠2, that is
∠2 = 18°

Step-by-step explanation:
Integers are just whole numbers.
So between 1.25 and 7.1 there is...

These are 6 integers.
Answer:
(1,1)
Step-by-step explanation:
Since y=x, we can say x=x^2-x+1. This means x^2-2x+1=0. x=1, y=1, thus your solution is (1,1).
Answer:
A
Step-by-step explanation:
Remember that triangle's area is 1/2 x b x h. But we have 2 congruent triangles so we have 2 x 1/2 x b x h. so the area of 2 triangles is b x h.
You should know the areas of other sides.
5 x 6 + 6 x 12 + 6 x 13 + 5 x 12
Simplify!
30+72+78+60
90+150
240
