The last option is correct. If two sides of a triangle are congruent, then the angles opposite those sides are congruent. This is probably because the sides are equal.
Answer:
15 cm²
Step-by-step explanation:
3(5)=15 cm²
The answer is probably 2 because if you plug in the numbers you would get
3x-4=-12 divided by -6 = +2.
Answer:
C. xy²
Step-by-step explanation:
You have to add the exponents:
(xy) exponent is 1
(x) exponent is 1
Combine the (x):
xy²
Answer:
A) x=40°
B) They have the same lengths.
Step-by-step explanation:
Since it is an isosceles triangle, both sides are the same. So if you add up all the angles of any triangle, it should always add up to 180°. There is a 50° angle and a right angle (90°) so you subtract 50 and 90 from 180 (180-50-90) and you get 40. X has to be 40° :)
