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! :)

A 15m long ladder reached a window 9m high from the ground on placing it against a wall at a distance x. Find the distance of th

Ilya [14]

Answer:

12 meters

Step-by-step explanation:

Given That :

Length of ladder = 15m

Height of wall =. 9 m

Using Pythagoras rule :

Adjacent² = hypotenus² - opposite²

Adjacent² = 15² - 9²

Adjacent² = 225 - 81

Adjacent² = 144

Adjacent = sqrt(144)

Adjacent, x = 12
