Answer:
38.7
Step-by-step explanation:
For this one we have the oppsoite and the hypotonouse
therefore we'll use SOH
let x= theta/the angle
sin(x)=7/11.2
x=38.68
38.7
Answer:
84
Step-by-step explanation:
first calculate the rectangle (6* 10 = 60) and then add that to the area of the triangles. 1/2(4) * 6= 2 * 6 = 12, and since there are two triangles: 12* 2 = 24, add that to the area of the rectangle and you get 84.
Answer:
∠3 = 60°
Step-by-step explanation:
Since g and h are parallel lines then
∠1 and ∠2 are same side interior angles and are supplementary, hence
4x + 36 +3x - 3 = 180
7x + 33 = 180 ( subtract 33 from both sides )
7x = 147 ( divide both sides by 7 )
x = 21
Thus ∠2 = (3 × 21) - 3 = 63 - 3 = 60°
∠ 2 and ∠3 are alternate angles and congruent, hence
∠3 = 60°
2 1/5 is equivalent to 2 2/10. 2 2/10 + 1 1/10 is 3 3/10. C is the answer.
