12 + 26 + 125 = 163
163 + 0.056(163) = 163 + 9.13 = 172.13
Answer:
(4/2 × 2/2 × 3/2) in.³ =3 in.³
Step-by-step explanation:
∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20
Answer:21
Step-by-step explanation: solve whats in the numerator then solve whats in the denominator then you divide
Answer:
77 degrees and 90 degrees
The angle d is shown as 90 by the perfect right angle. The angle e has to equal 180 when added to f. So 180-103=77.
