Answer:
64°
Step-by-step explanation:
∠RQP = 46°
∠PRQ = 180° - 110° = 70°
∠PRQ + ∠RQP + <u>∠RPQ</u> = 180°
70° + 46 + <u>∠RPQ</u> = 180°
116° + <u>∠RPQ</u> = 180°
Find <u>∠RPQ</u>
<u>∠RPQ</u> = 180° - 116° = 64°
Answer:
B
Step-by-step explanation:
770 × 12 × 12 = 110880 →10%→10÷100=x÷110880
100x=1108800
x=1.1088×10 in power of four
Answer:
x=24
y = 8 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use sin and cos
sin 30 = opposite/ hypotenuse
sin 30 = y/ 16 sqrt(3)
Multiply each side by 16 sqrt(3)
16 sqrt(3) * sin 30 = y
16 sqrt(3) * 1/2 = y
8 sqrt(3) = y
cos 30 = adjacent/ hypotenuse
= x/16 sqrt(3)
Multiply each side by 16 sqrt(3)
16 sqrt(3) cos 30 = x
16 sqrt(3) * (sqrt(3)/2) = x
8 * sqrt(3)*sqrt(3)
8 * 3 = x
24 =x
