Two angels re supplementary. The larger angle is 48 degrees more than the 10 times the smaller angle. Find the measure of each a
evablogger [386]
Supplementary angles are two angles that add up to 180°.

STEP 1:
find the value of x

x= smaller angle
10x + 48= larger angle

Add the two angles above to equal 180.

x + (10x + 48)= 180
combine like terms

11x + 48= 180
subtract 48 from both sides

11x= 132
divide both sides by 11

x= 12° smaller angle


STEP 2:
find the value of the second angle

=10x + 48
=10(12) + 48
=120 + 48
=168° larger angle


CHECK:
12° + 168°= 180°
180°= 180°


ANSWER: The smaller angle is 12° and the larger angle is 168°.

Hope this helps! :)

Answer: First option

Step-by-step explanation:

When you divide you switch the numerator and denominator, so it becomes (15y^2)/30x. You can divide the top and bottom by 15 so you get y^2/2x

The triangles are similar. Write a similarity statement for the triangles.
Alecsey [184]

Answer:

we know that

If two figures are similar, then its corresponding sides are proportional and its corresponding angles are congruent

In this problem

Triangles XZY and VZW are similar

therefore

corresponding angles are congruent

∠XZY≅∠VZW

∠ZXY≅∠ZVW

∠XYZ≅∠VWZ

corresponding sides are proportional
