210/10 = 21
7*21=7(20+1)=140+7=147
147 is 70% of 210, as 7/10 of 210 is 147.
Answer:
It is not a right triangle
This is a scalene triangle
Step-by-step explanation:
A right triangle is a triangle in which one of the angles is a 90∘ angle. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
This cannot be obtuse b/c it does not add up to 180.
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different).
Answer:
There is a large outlier.
Step-by-step explanation:
Answer:
90°
Step-by-step explanation:
5x+20=9x
20=4x
5=x
<DEG=5x+20+9x=5(5)+20+9(5)=25+20+45=90
Answer:
144
Step-by-step explanation:
The answer is 144 because we can take any multiple of 72, the LCM of 18, 24, and 36, but 72 is not a perfect square. So, we go to the next multiple, 144, which is a perfect square, so the answer is 144. Hope it helps!
