Solve the right triangle, ΔABC, for the missing sides and angle to the nearest tenth given angle B = 27° and side c = 15.

nignag [31]

Answer:

Part 1) $C=90\°$

Part 2) $A=63\°$

Part 3) $b=6.8\ units$

Part 4) $a=13.4\ units$

Step-by-step explanation:

step 1

Find the measure of angle C

we know that

The triangle ABC is a right triangle

Angle C is a right angle

therefore

$C=90\°$

step 2

Fin the measure of angle A

we know that

In the right triangle ABC

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

we have

$B=27\°$

substitute

$27\°+A=90\°$

$A=63\°$

step 3

Find the length side b

we know that

In the right triangle ABC

$sin(B)=b/c$

$b=(c)sin(B)$

substitute the given values

$b=(15)sin(27\°)=6.8\ units$

step 4

Find the length side a

we know that

In the right triangle ABC

$sin(A)=a/c$

$a=(c)sin(A)$

substitute the given values

$a=(15)sin(63\°)=13.4\ units$

What is 23/35 simplified?

Kobotan [32]

There is no least common enominator for this answer due to the fact that these numbers don't share a common factor (23 is odd number with only two factors: 1, 23; while 35 is odd number with 4 factors: 1, 5, 7, 35) other than 1.

*But if you do 1/1, it will be 1; so this won't work properly.

So the answer is 23/35.

nate's quiche is cut into 7 equal parts. only 3/7 is left. he wants to give 3 of his friends equal part. write 3/7 as the sum of

Stolb23 [73]

The problem is to write 3/7 as the sum of equal parts, that is a sum of fractions:
1/7 + 1/7 + 1/7 = 3/7
note that we are only adding the numerator, the upper part.

George weighed 170 lbs when he started college. If he gains just 0.25 lbs after each month for 4 years of college, how much will

Marina86 [1]

He would gain 12lb. for 4 years and the total would be 182lb.

For 6 years it would be 18lb.

The first thing you need to do is make the 6 years into months = 12 x 6 = 72
Then multiply 72 by 0.25 = 18lb. + 170 = 188lb.

The answer would be 188lb. for 6 years
and 182 for 4 years.
