Answer:
If ABC and DEF are similar triangles such that ∠A = 47° and ∠E = 63°, then the measures of ∠C = 70°. Is it true? Give reason. ∴ Given statement is true. Question 3. Let ∆ABC ~ ∆DEF and their areas be respectively 64 cm 2 and 121 cm 2. If EF = 15.4 cm, find BC. Question 4. ABC is an isosceles triangle right-angled at C. Prove that AB 2 = 2AC 2.
Step-by-step explanation:
Hi.
C =<em> </em>2<em />π<em>r
</em>
<em>r = </em>16
2π(16) = 100.48 (π = 3.14)
The clock will travel 100.48 in in one hour.

Answer:-7^2(negitive seven to the second power)
Step-by-step explanation:
I believe you will sub. in 3 for t so h=-16(3)^2 + 60(3)+6. then you will just solve!
h=-16(9)+60(3)+6
h= -144 + 180 + 6
h= 42
so the answer to your question is c. 42 Feet
Hope this helps! :)
We know that vertically opposite angles are equal.
So, k = 131° [Vertically opposite angles]
and g = 43° [Vertically opposite angles]
We know that linear pair of angles are supplementary (180°).
So, h + 43° = 180° [Linear pair of angles]
=> h = 180° - 43°
=> h = 137°
and m + 131° = 180° [Linear pair of angles]
=> m = 180° - 131°
=> m = 49°
