Solve0.9(7x + 14) = 1.5 - (x + 2)

Mathematics
1 answer:
Triss [41]3 years ago
7 0

\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)

\\ \sf\longmapsto 6.3x+12.6=1.5-x-2

\\ \sf\longmapsto 63x+12.6=-x-0.5

\\ \sf\longmapsto 63x+x=-0.5-12.6

\\ \sf\longmapsto 64x=-13.1

\\ \sf\longmapsto x=\dfrac{-13.1}{64}

\\ \sf\longmapsto x=0.2

Find the measure of each angle indicated. Round to the nearest tenth.
Sladkaya [172]

Answer:

D

Step-by-step explanation:

So we want to find<em> θ. </em>We are already given the hypotenuse and the side length opposite to <em>θ. </em>Therefore, we can use the trig function sine to find <em>θ. </em>

Recall that:

\sin(\theta)=opp/hyp

Plug in 10.2 for the opposite side and 15 for the hypotenuse:

\sin(\theta)=10.2/15

Solve for <em>θ. </em>Use a calculator:

\theta=\sin^{-1}(10.2/15)\\\theta\approx42.8436\textdegree

The answer is D.
