For number 15, all you need to do is multiply 36 by 25 which gets you 900 square yards. For #16, you would also want to use multiplication, 3 * 39 ($117) , 4 * 15 ($60) and 27 * 2 ($54). Now add them together, 54 + 117 = 171 + 60 = $231. And finally break down the number 309 million, 058 thousand, 304 hundred. Four, eight and, nine need to be in the ones place. So you have 309,058,304, C.

Answer:
Step-by-step explanation:
The question lacks the required diagram. Find the diagram attached below;
According to the first triangle, taking 30° as the reference angle, the opposite side of the triangle will be 5 and the adjacent will be the unknown side "b"
According to SOH, CAH, TOA;
tanθ = opposite/adjacent (using TOA)
Given;
θ = 30°, opposite = 5 and adjacent = b
tan30° = 5/b
b = 5/tan30°
b = 5/(1/√3)
b = 5*√3/1
b = 5√3
According to the 45° triangle, the opposite side of the triangle will be d and the hypotenuse will be 7
Using SOH;
sinθ = opposite/hypotenuse
Given;
θ = 45°, opposite = d and adjacent = 7
sin45° = d/7
d = 7sin45°
d = 7(1/√2)
d = 7/√2
Rationalize 7/√2
= 7/√2*√2/√2
=7√2/2
Hence the value of d is 7√2/2
