<u>Answer:</u>

For n = 1, 150

for n = 2, 1164

<u>Step-by-step explanation:</u>

The answer for n = 1, is,

$\int_{0}^{6}(2 \times x^{2} + 1)\times dx$

= $[2 \times \frac {x^{3}}{3} + x]_{0}^{6}$

=150

The answer for n = 2 is,

$\int_{0}^{12}(2 \times x^{2} + 1)\times dx$

= $[2 \times \frac {x^{3}}{3} + x]_{0}^{12}$

= 1164

Let x represent the measure of angle ACD, and let y represent the measure of angle BCF.

Liono4ka [1.6K]

We know that
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°

the answer Part 1) is x=124°

Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°

the answer Part 2) is y=44°
