Answer:
390.66 meters
Step-by-step explanation:
perimeter = 2(87) + 3.14(69)
= 174 + 216.66
= 390.66
8x^2 = 96x
8x^2 - 96x = 0
8x(x - 12) = 0
8x = 0....x = 0
x - 12 = 0
x = 12
ur number is 12
A
you have to solve x^2+x-5=0
So x=(-1 +/- sqrt(1^2+4*1*5))/2
x=(-1 +/- sqrt(21))/2
If these are the given choices of the above problem,
a. one side and one angle are equal.
<span>b.three sides are equal </span>
<span>c.two angles are equal </span>
<span>d. three angles are equal
Two non-right triangles are congruent when B. THREE SIDES ARE EQUAL.
Two triangles are congruent if:
1) All corresponding sides are equal (SSS)
2) A pair of corresponding sides and the included angle are equal (SAS)
3) A pair of corresponding angles and the included side are equal (ASA)
4) A pair of corresponding angles and a non-included side are equal (AAS)</span>
