Ivan is 162.4 centimeters tall and is building a tower out of cans that he wants to be as tall as he is. He wants to know how many cans he will need, but he forgot to measure the length of 1 can. He knows that 10 cans are 56 centimeters tall. If he starts building the tower of cans on a stool that is 28 centimeters tall, how many cans does he need for his tower?

Answers

Answer:

Ivan will need 24 cans. 56/10 = 5.6. Each can is 5.6 cm tall. 162.4-28 =134.4

134.4/5.6 = 24

Answers

Answer:

The area of a parallelogram is base x height. You multiply the base and height (represented as b and h) to get the area of the parallelogram.

In the first question, the base and height is already given to you so, 2x6=12.

12yd squared is the area for the first one.

Now lets do the second one. The base and height is also given to you so do, 6x4=24.

24m squared is the area of the second one.

Use the diagram to find the measure of ∠PML.

Answers

Answer:

31 degrees

Step-by-step explanation:

We know that if the angle P is equal to 121+x=180 because when it is reflected, they both have to add up to 180. Therefore, P is equal to 59 degrees. We know that angle L is 90 degrees because there is a square. Therefore, we have to do 180-59-90 to find angle PML. 180-149. Angle PML is equal to 31 degrees.

[WILL GIVE BRAINLY] An angle measures 122° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

The measure of the angle will be equal to 58°.

What is the supplementary angle?

The supplementary angles are defined as the angles whose sum is equal to 180°

here the angle is 122° degrees more than its supplementary angle.

We know that the sum of the two supplementary angles is given as:-

Suppose the known and the unknown angles are A and B respectively.

∠A  +  ∠B  =  180°

122  + ∠B  = 180°

∠B  =  180-122= 58°

Hence the measure of the angle will be equal to 58°.
