Answer:
45
Step-by-step explanation:
Triangles equal up to 180 degrees therefore you do the following to solve this equation. So you have 80 and 55. So you add 80 to 55 and you get 135. Now you subtract 180 by 135 and that equals 45. So x=45. I will write it out as well.
55+80=135
180-135=45
x=45
To check.
80+55+45=180
Answer:
Blank 1: 64° (or 32°, depending on what the label applies to)
Blank 2: 42
Step-by-step explanation:
It is a common mistake to believe you have solved the problem when you have found the value of the variable(s) in the problem. You have correctly found the values of n (42) and m (9). However, that is not what the problem is asking for.
We cannot tell if the value (1/2n+11)° is referring to angle DAB, or to angle CAB. In any event, (1/2n+11)° = (1/2×42 +11)° = 32°.
If that is angle CAB, then angle DAB is twice that value, 64°.
If that is angle DAB, then angle DAB is 32°.

The side length CD is the same as any other side length in a rhombus, so ...
CD = 4m+6 = 4×9 +6
CD = 42 . . . . units
Answer:
m=-4/5 and b=1
Step-by-step explanation:
The original formula is y=mx ±b and when asked to find those they are placed in the formula.
4/5x + 5 < -3 (multiply the inequality by 5 to get rid of fraction)
4x + 25 < -15 (subtract 25 from both sides)
4x < -15 - 25
4x < -40
x < -10
or
4/5x + 5 < -3 (subtract 5 from both sides)
4/5x < -3-5
4/5x < -8
x < -8/(4/5)
x < -8 * 5/4
x < - 40/4
x < -10
