Angle a and b are supplementary angles which means that when added they equal 180.
so we must set our equation equal to 180.
8x+74+2x+56=180
which simplifies to 10x+130=180
then subtract 130 from both sides.
10x=50
x=5
So we plug in 5 to find the measure of b.
2(5)+56=b
10+56=b
66=b
the measure of angle b is 66 degrees
Answer:
Let
a
=
8
and
b
=
8.5
Let the angle between
a
and
b
be
θ
Let the unknown side be

Step-by-step explanation:
For a point to be a relative extreme, there must be points on both sides that are not as extreme. That is, the ends of the interval may be extreme values, but do not qualify as <em>relative</em> extrema, since there are not points on <em>both sides</em>.
In the interval [-3, 3], the relative extrema are the turning points.
The relative minimum is at y = -9 on the y-axis.
The relative maxima are at y = -6, between 1 and 2 on either side of the y-axis.
Terms are the numbers and variables that are usually separated by an addition sign or a subtraction sign. In the expression 2x, 3y, 5z, and 4 are all terms.
Variables are the letters that come after a number. They represent the unknown number in the equation. The x, y, and z in the expression are the variables.
Coefficients are the numbers in front of the variables. For example, 2, 3, 5, and 4 are the coefficients.
The constants are the "signs" in between the terms. These include the addition sign and the subtraction sign.
