the area of a rectangular decks is 680 square feet. the decks width is 17 feet. what is its perimeter ?
Ket [755]
The perimeter is 114 square feet. To solve this, first you divide 680 by 17, which equals 40. So the length is 40. The formula for perimeter is 2L+2W. This means you take the length and multiply it by 2, and do the same for the width, then add them together. So the equation would be:
2(40)+2(17)=Perimeter
80+34=Perimeter 
The final answer is 114 square feet.

21 and 22 are complementary angles.
Bumek [7]

The measure of angle 2 is \angle 2=14^{\circ}

Explanation:

Given that \angle 1 and \angle 2 are complementary angles.

Also, the measure of angle 1 is \angle 1= 76^{\circ

We need to determine the measure of \angle 2

Since, we know that the complementary angles add up to 90°, then the angles \angle 1 and \angle 2 add up to 90°.

Thus, we have,

\angle 1+\angle 2=90^{\circ}

Substituting the value of \angle 1 in the above expression, we have,

76^{\circ}+\angle 2= 90^{\circ}

Subtracting both sides by 76°, we get,

\angle 2 = 90^{\circ}-76^{\circ}

Simplifying, we have,

\angle 2 = 14^{\circ}

Thus, the measure of angle 2 is \angle 2=14^{\circ}
