Mathematics
1 answer:
sweet [91]3 years ago
7 0

Answer:

no

Step-by-step explanation:

to find out whether a triangle is a right triangle we can use the pythagorean theorem

a²+b²=c²

a= one side of the triangle

b= one side of the triangle

c= the hypotenuse (or biggest side )

21^2+ 72^2= 76^2

441+ 5184= 5776

5625 = 5776  X

since the sums do not equal this means that it is not a right triangle.

i hope this helps!!

Please help. Sooooo confused. GOAL is a quadrilateral in which GO is parallel to AL. If the measures of angle G=angle O = 40 deg
DanielleElmas [232]

Answer:

Angle A and L are 140 degrees each.

Step-by-step explanation:

Since GO and AL are parallel to each other, we can use the same side interior theorem to figure out angle A and L. Let's focus on GA first. We know that same side interior angles are supplementary (sum is 180 degrees). We know angle G is 40 degrees, so to figure out angle A, you do 180-40 which equals 140. So angle A is 140 degrees. You repeat this process for OL and you should also get 140 degrees for L.
