In right △ABC with right angle B, m∠A=(3x−8)° and m∠C=(x−2)°.

julsineya [31]

Answer:

<A = 67

Step-by-step explanation:

The three angles of a triangle add up to 180 degrees. We know a right angle is 90 degrees.

<A + <B + <C = 180

3x-8 + 90 + x-2 =180

Combine like terms

4x-10+90 = 180

4x+80 =180

Subtract 80 from each side

4x+80-80=180-80

4x=100

Divide each side by 4

4x/4 = 100/4

x=25

But we want to know <A

<A = 3x-8

Substitute x=25

=3(25) -8

=75-8

= 67

Please help me!!!!!!!!:(

Answer:

24% chance

Step-by-step explanation:

First, find the total number of graduates in the table, that number is 2610, that will be your numerator.

You will look at the table for the total number of students, that is 10730, that will be the denominator.

Now divide the smaller number/numerator (2610) by the larger number/denominator (10730)

$\frac{2610}{10730}$ = 0.2432432...

Then, multiply by 100 to get the percentage: 24.32432...%

Now, round to the nearest percentage: 24%
