Measures of an angle and five times it’s complement is 298 what is the measure of the angle
Marianna [84]
Complementary angles add up to 90<span>°, therefore, let's say the angles are "a" and "b".

so the sum of "a" plus " 5 times its complement", that is 5 times "b" is 298, so a + 5b = 298.

now, if a + b = 90, that means b = 90 - a.

therefore

</span>\bf a+5b=298\implies a+5(90-a)=298\implies a+450-5a=298&#10;\\\\\\&#10;-4a=-152\implies a=\cfrac{-152}{-4}\implies a=38<span>

Sammy has 2 pairs of jeans, 3 pairs of black pants, and 1 skirt. She also has 2 pink shirts, 4 striped shirts, and 2 hooded swea
Semenov [28]

I'm not too sure if this a a question for school but i think it really depends on what Sammy wanna wear. I would also say she may wear black pants and a striped shirt because of the amount she has of them. All the other clothes have only two pairs, So because she has more than two pairs for black pants and striped, it means that she likes that outfit of the black pants and striped shirt so she will most likely wear them.
