151 - 11 = 140
140 ÷ 2 = 70
70 + 11 = 81
Jack is 81 years old.
Pricilla is 70 years old.
thy get 55/75 and you want to know x/300
55/75 x X/300
cross multiply 55 x 300 = 16500
divide that by 75
16500/75 = 220
x = 220
they will get $220
Answer:
C. 106
Step-by-step explanation:
Angles 2 and 6 are corresponding angles so they're both 74. So you just subtract 74 from 180 to get 106.
(a) angle TPR = 90° - 30° = 60°
Reason: because the PTR is a right angled triangle.
(b) sin 30° = PR/14
PR = sin 30° × 14 = 7in.
(c) tan 30° = 7/TR
TR = 7/tan30° = 7 / (1/(#3))
= 7#3 in.
# : square root
(d) sin 45° = 7/PQ
PQ = 7/sin 45° = 7 / (1/(#2))
= 7#2 in.
Hope it helped!
