Answer:
19
Step-by-step explanation:
f(x) = 2x^2 +1
Let x =3
f(3) = 2 (3)^2 +1
= 2 *9 +1
= 18 +1
= 19
Answer:
∠QTR = 44°
Step-by-step explanation:
Given ∠PTQ = ∠RTS = 35°, then
∠PTQ + ∠QTR + ∠RTS = ∠PTS ← substitute values
35 + ∠QTR + 35 = 114, that is
70 + ∠QTR = 114 ( subtract 70 from both sides )
∠QTR = 44°
P = 2(L + W)
P = 264
W = 54
264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards
Answer:
Step-by-step explanation:
The step you need next is RQ = RQ.
When I learned this stuff, saying that RQ = RQ is the reflexive property.
Now you have
RP = RS Given
<PRQ = <SRQ The result of a bisected angle.
RQ = RQ A line is always equal to itself.
So the triangles are congruent. The rest follows as stated.
