If the measure of an angle is 78 less than the measure of its compliment, what is the measure of the angle?
aliina [53]
Complementary angles add up to 90'
So let X= angle 1
         Y=angle 2
So x+y=90
let x=y-78
so(y-78)+y=90
y-78+y=90
2y-78=90
2y=90+78
2y=168
y=168/2
y=84
x=y-78
so x=84-78
x=6
And 6+84=90
So the measure of the angle is 6 degrees.
Hope i helped!

4. Identify the term with coefficient -3 in the expression:<br> 9a3 + 4b2 - 3c + 11
Mrrafil [7]

Answer:

-3 is the coefficient of c.

Step-by-step explanation:

The given expression is :

9a³ + 4b² - 3c + 11

We need to find the term with coefficient -3 in the expression.

The coefficient is defined as a number or quantity placed with a variable.

The coefficient of a³ = 9

The coefficient of b² = 4

The coefficient of c = -3

Hence, -3 is the coefficient of c.
