Answer:
True
Step-by-step explanation:
We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!
Range should be (-∞ , 10]
answer is C.
Step-by-step explanation:
CDE = 2x, DEF = x
hexagon = 720°
720 = 115 + 145 + 160 + 90 + 2x + x
720 = 3x + 510
720 - 510 = 3x
210 = 3x
x = 210 ÷ 3
x = 70°
CDE = 2x
= 2(70)
= 140°
Answer:
(i) In triangle RTO and QSR
Given,
⇒∠RTO=∠OSR=90
o
(QS⊥PR and RT⊥PQ)
⇒QS=RT
⇒QR=RO ....Hypotenuse
∴△RTQ≅△QSR ....RHS criterion
(ii) By using part(1) of a solution, we get
∠TQR=∠SRQ ....By C.P.C.T
⇒∠PQR=∠PRQ
Step-by-step explanation:
Multiply
ignoring the square root sign for a moment to get
. Simplify
to get 20. so, your answer is B.
