Answer:
27°
Step-by-step explanation:
- A tangent meets a radius at 90°
- Angles in a trainable sum to 180°
- 180 - 90 - 63 = 27°
20/35 and 21/35. The common denominator is 35.
Hello from MrBillDoesMath!
Answer:
3
Discussion:
Let the number be "n",
2n + 15 = 21 => subtract 15 from both sides
2n = 21 - 15 = 6 => divide both sides by 2
n = 6/2 = 3
Check: Start with 3. Double it (gives 6), add 15 to it ( 6 + 15) which gives 21/
Thank you,

Answer:
In the picture attached, the question is shown.
a) Applying Pythagorean theorem to triangle ABC, and solving for AC:
CB² + BA² = AC²
5² + 12² = AC²
√169 = AC
13 cm = AC
b) Applying Pythagorean theorem to triangle ACD, and solving for AD:
CD² + AC² = AD²
5² + 13² = AD²
√194 = AD
13.9 cm = AD

The answer is B
Step-by-step explanation:
because it snows 4 more time
if 30mins is 7/8 then 3
more of that is 4 times
