What are the missing angle measures in triangle ABC?

Mathematics
2 answers:
Finger [1]3 years ago
5 0

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°

PLZ HELP ASAP! IM FAILING SO PLEASEEEE
UkoKoshka [18]

Answer: B

You can find slope by using the slope formula. Because we are already given two coordinate points, we can use that to find our slope. The slope formula is \frac{y^{2}-y^{1}  }{x^{2}-x^{1} }. This also refers to \frac{5-(-5)}{0-4} or 10/-4 or -5/2. Any coordinate with the x-value as 0 means that that coordinate is the y-intercept. Because (0,5) has 0 as its x-value, the y-intercept is 5.

Find the prime factors.<br> 7) 48
FinnZ [79.3K]

Step-by-step explanation:

48 = 48 \times 1 \\ 48 = (24 \times 2) \times 1 \\ 48 = (12 \times 2) \times 2 \times 1 \\ 48 = (6 \times 2) \times 2 \times 2 \times 1 \\ 48 = (3 \times 2) \times 2 \times 2 \times 2 \times 1

How to solve -27/x^15
kompoz [17]

Answer:

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}

Step-by-step explanation:

<em>If you just want to simplify -27/x^15, it is not very difficult. Here is the simple way.</em>

<em />

Given the expression

\frac{-27}{x^{15}}

solving

\frac{-27}{x^{15}}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}

=-\frac{27}{x^{15}}

Therefore,

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}
