∠ Given are (x + 18)° , x° , 4x° and one Angle is 90° as per diagram
Let ,
1st∠ = (x + 18)°
2nd∠ = x°
3rd∠ = 4x°
so ,

substituting x = 12 at the place of x .
= x° + 18°
= 12° + 18 °
1st∠ = 30°
__________________________________
= x°
2nd∠ = 12°
__________________________________
= 4x°
= 4(12)°
3rd∠ = 48°
The missing length is 51.5, I hope this helps :)
Tan=sin/cos
So sin a= 7
Cos a= 24
Answer:
25
Step-by-step explanation:
<em><u>Formula</u></em>
Generally the formula is written as Area = side * side which is
<em><u>Givens</u></em>
side = s = 5
<em><u>Solution</u></em>
Area = 5 * 5
Area = 25 square inches.
