Answer:
C. 11
Step-by-step explanation:
Substituting, we have ...
8{80, 19, 11} ?= 88
{640, 152, 88} ?= 88
The value from the set that makes the equation true is x = 11.
_____
<em>Alternate methods of solution (other than substitution)</em>
It can be easier to make use of your knowledge of factoring:
8x = 8·11
x = 11
Or to make use of your knowledge of numbers (place value):
8·10 = 80
so x will not be very different from 10.
Answer:
<h2>
x = 67°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is allways 180°
So:
x + 53° + 60° = 180° {subtract 113° from both sides}
x = 67°
Answer:
∠1 only
Step-by-step explanation:
Complementary angles:
- sum to 90°
- form a right angle
The only angle (that's an answer choice) that helps form a right angle with angle 2 is angle 1, thus making it the correct answer.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
