Mathematics
1 answer:
Rudik [331]3 years ago
7 0

Answer:

5*\frac{1}{2}

Step-by-step explanation:

We have a picture and are being asked to identify the multiplication problem that represents it.

So we have 5 triangles, all of which are color-coded in red, but only half of them are filled. When multiplying, the number that is before the * sign is the amount there is, while the number that is after the * is the amount going to multiply the amount of items there are. So looking at the picture, we can see 5 triangles, therefore :

5 *

2 * 1/5 is scratched out as an answer. As is starts with 2.

As for the second number, we acknowledge that all triangles are half in red, therefore the number is 1/2.

5 * 1/2

Scratching all other answers.

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the four angles formed
vitfil [10]
We have
angle 1=72 degrees

see the attached picture to better understand the problem

we know that
<span>Vertical angles are congruent
</span>angle1=angle3 \\ angle2=angle4
<span>
and

adjacent angles are supplementary
</span>angle2+angle1=180 \\ angle3+angle4=180
<span>
if the measure of one of the angles is </span>72 degrees and straight lines equal 180<span> degrees you have to
subtract </span>72 from 180
so
angle 2=180-72 \\ angle 2=108 degrees

therefore
angle 3=amgle 1 \\ angle 3=72 degrees

angle 4=amgle 2 \\ angle 4=108 degrees

the answer is

the measures of the other three angles are
108, 108 and 72 degrees
