Find the measures of two complementary angles if one angle is 18degrees more than three times the other angle.

1 answer:

5 0

We call these angles a and b.
we have the sum a+b=90
and 3b+18=a
So we have this equation by replacing
3b+18+b=90 or 4b=72 or b=18 and a=72

"Let A = the number of model A grates and let B = the number of model B clock grates. In this application, write the constraint

Mashcka [7]

Answer:

In this problem, if we solve it by linear programming one of the conditions does not satisfy which is - number of B should be produced at least 180 in order to meet backlog. This means for B only we need 180* 4 = 540 lbs of iron where as daily supply is only of 100 lbs.

for this option (3) looks viable i.e. 3A + 4B <= 100

In the above figure, m&angle;P = 125° and m&angle;Q = 5x. If angles P and Q are supplementary angles.

GalinKa [24]

Answer:

C. x = 11, m∠Q = 55º

Step-by-step explanation:

125 + 5x = 180

5x = 55

x = 11

5x = 55

C. x = 11, m∠Q = 55º
