Step-by-step explanation:
4+7=11
11+(7+4)=22
22+(7+8)=37
Every step 7+4n you must add
Answer:
x = -3
Step-by-step explanation:
3x –7 = -16
3x = -16 + 7
3x = -9
x = -3
So you find out how many triangles are in this by taking a point and making a line to another point that isn't on the same line. this one has 3 triangles. each triangle is 180*(using multiplication symbol for degree symbol).you do this to find out what the number of angles adds up to. 180* multiplied by 3 equals 540*. Then if you add up all the angles you have 400*. 540 - 400 equals 140*. So the final angle is 140*. Hope this helps!
<span>here are the answer choices
m∠ABC=32°
m∠ABC=64°
m∠ABC=90°
m∠ABC=128°
</span>∠ ABC<span> is less than 90</span>° so the 3rd and 4th option is out.
The most likely answer is 64°. m∠ABC = 64°
32° x 2 = 64°
