Answer: 4
Step-by-step explanation:
Not 100% sure but Eric can be 18.5 years old and his father can he 51.5 years old.
52 - 33 = 19; 52 + 19 = 71
51 - 33 = 18; 51 + 18 = 69
51.5 - 33 = 18.5; 51.5 + 18.5 = 70
I hope this helps.
Step-by-step explanation:
By Cosine rule, we have
s² = t² + u² - 2(t)(u)(cosS)
=> cosS = (t² + u² - s²)/2tu
=> cosS = (58² + 27² - 50²) / (2 * 58 * 27) = 0.5086.
Therefore S = cos^-1(0.5086) = 59.4° (1d.p.)
i really cant see what it says sorry
Since it is a parallelogram cente at point T,
then the measure of PT is equal to the measure of TR. And the measure of QT is
equal to the measure of TS.
PT = TR
a + 4 = 2a
4 = 2a -a
a = 4
PT = TR = 8 units
QT = TS
b = 2b -3
3 = 2b – b
b = 3
<span>QT = TS = 3 units</span>
