Answer:
yes; you can just remember that all the angles on a triangle equal 180 so just add the two angles, subtract from 180 to get your last angle degrees.
Answer:
The measure of the complement is 30°
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
Two angles are complementary if their sum is equal to 90 degrees
Let
x -----> the measure of an angle
we know that
180°-x=4(90°-x)
Solve for x
180°-x=360°-4x
4x-x=360°-180°
3x=180°
x=60°
Find the complement
90°-x=90°-60°=30°
Answer:4 dozens of video games would cost $1956
Step-by-step explanation:
An electronic store prices 3 dozen video games at a total of 1467. A dozen of video games is 12. Therefore, the total number of video games whose cost is 1467 is 12 × 3 = 36
if each video game costs the same amount, then the cost of one video game would be
1467/36 = $40.75
The total number of video games in 4 dozens of video game would be
4 × 12 = 48
Therefore, the total cost of 48 video games would be
48 × 40.75 = $1956
