Answer:
47°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles
124° is an exterior angle , thus
77 + ? = 124 ( subtract 77 from both sides )
? = 47°
Answer:
18.5÷11.99 is correct the answer is most likly option B
STR is a triangle as shown in the picture. If Luke decided to subtract 128º from 180º, that's because he understood that the sum of the internal angles in a triangle is 180º, and therefore the angles RST and TRS together make 128º.
As a result, RST will be
128º - TRS
where TRS is the angle at R, as shown in the picture
I believe it's the 3rd one. It's a really tricky question sorry if you get it wrong
Answer:
Yes
Step-by-step explanation:
Linear means a line, and x is not squared or anything in this equation. If you were to graph it, it would be a line.
