An angle measures 70° less than the measure of its complementary angle. What is the measure of each angle?

Elina [12.6K]

Answer:

Larger angle: 80 degrees

Smaller angle: 10 degrees

Step-by-step explanation:

complementary angles = two angles that add up to 90 degrees

x = larger angle

x + x - 70 = 90 Add like terms

2x - 70 = 90 Add 70 on both sides

2x = 160 Isolate the variable by dividing 2 on both sides

x = 80

x = larger angle , 80 degrees

x - 70 = smaller angle , 10 degree

Given: K=2∙33∙11∙172and M=3∙11∙173<br><br> Evaluate 18·M÷K.

gayaneshka [121]

Answer:

1557/1892

Step-by-step explanation:

Your calculator can do this:

$\dfrac{18M}{K}=\dfrac{18\cdot 3\cdot 11\cdot 173}{2\cdot 33\cdot 11\cdot 172}=\dfrac{18\cdot 173}{2\cdot 11\cdot 172}\\\\=\dfrac{1557}{1892}$
