Answer:
110
Step-by-step explanation:
x=110 due to congruent angle
(suggest u to draw 2 straight lines and observe differences and similarities of the 4 angles)
The answer is 18. The two sides are the same length, so you set the two sides equal to each other and solve for x. After finding x, you plug in the number into the base expression and you get the base length.
Answer:
3.25 and -2.651639344262295...
Step-by-step explanation:
if 0.5(r + 2.75) = 3, then r = 3.25
if 30.5(r + 2.75) = 3, then r = -2.651639344262295...
<u>I would appreciate Brainliest, but no worries.</u>
All quadrilateral angles have to add up to a total of 360°, so we just need to add the angles we already have and subtract that from 360.
135+90+80=305
360-305=55 so your answer is 55!
