PLS ANSWER QUICK I WILL GIVE BRAINLIEST

Mathematics
1 answer:
NISA [10]3 years ago
8 0

Answer:

B

Step-by-step explanation:

First, we are decreasing the number so it has to be a decrease.

Next, we divide 7/31 and get around 0.23, which also represents 23 percent.

This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.

We get 100 - 23 = 77, and because it is a decrease we get B.

Right △ABC has its right angle at C, BC=4 , and AC=8 .
PolarNik [594]

Answer:

Part A) sin(A)=\frac{\sqrt{5}}{5}

Part B) tan(B)=2

Part C) sec(A)=\frac{\sqrt{5}}{2}

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the length side AB (hypotenuse of the right triangle)

Applying the Pythagorean Theorem

AB^2=BC^2+AC^2

substitute the given values

AB^2=4^2+8^2

AB^2=80

AB=\sqrt{80}\ units

simplify

AB=4\sqrt{5}\ units

step 2

Find sin(A)

we know that

In the right triangle ABC

sin(A)=\frac{BC}{AB} ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

sin(A)=\frac{4}{4\sqrt{5}}=\frac{\sqrt{5}}{5}

step 3

Find tan(B)

we know that

tan(B)=\frac{AC}{BC} ----> by TOA (opposite side divided by adjacent side)

substitute the values

tan(B)=\frac{8}{4}=2

step 4

Find sec(A)

we know that

sec(A)=\frac{1}{cos(A)}

cos(A)=\frac{AC}{AB} ----> by CAH

so

sec(A)=\frac{AB}{AC}

substitute the values

sec(A)=\frac{4\sqrt{5}}{8}

simplify

sec(A)=\frac{\sqrt{5}}{2}
