Answer:

  (a) x = 22

  (b) 46°

  (c) 44°

  (d) 180°

Step-by-step explanation:

Because the sum of the interior angles of a triangle is 180°, we know that the sum of the acute angles in a right triangle is 90°.

<h3>(a) </h3>

The sum of the marked acute angles is 90°.

  2x +(3x -20) = 90

  5x = 110 . . . . . . . . . . add 20, collect terms

  x = 22 . . . . . . . . . divide by 5

__

<h3>(b) </h3>

∠CBA = (3x -20)° = (3·22 -20)° = 46°

__

<h3>(c)</h3>

∠CAB = 2x° = 2(22)° = 44°

__

<h3>(d)</h3>

The sum of a triangle's interior angles is 180°.

Answer:

Option D

Step-by-step explanation:

From the spinner we see there are 5 colours in there.

These are;

Green, Yellow, Red, Purple, Blue.

This means that when it is spinned, there's possibility of getting only one colour per spin.

Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.

This means, all possible outcomes will be 5 × 2 = 10 outcomes.

With each colour possibly showing up with either tail or head.

Correct answer is Option D as it has 10 possible outcomes in the correct order.

tell me anything you know about my hero academia :&gt; And does anyone know what 41 = -3y + 11 by any chance its ok if you don't
sdas [7]

Answer:

y=-10

Step-by-step explanation:

In this problem you're trying to figure out what y equals.

First you subtract 11 from both sides.

30=-3y

Then, you divide each side by -3 to find y.

-10=y

y=-10

3.) mr. smith’s class sold wrapping paper for $3.50 each and mr. davis’ class sold magazines for $2.75 each. together, the class
igor_vitrenko [27]

Answer:

The number of wrapping paper sold was 32 and the number of magazines sold was 40

Step-by-step explanation:

Let

x ----> the number of wrapping paper sold

y ----> the number of magazines sold

we know that

The classes sold 72 items

so

x+y=72 ----> equation A

The classes earned $222 for their school

so

3.50x+2.75y=222 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is (32,40)

see the attached figure

therefore

The number of wrapping paper sold was 32 and the number of magazines sold was 40
