Answer: (1,1)
Step-by-step explanation:
The measure of angle 1 and 2 should add up to 180°, because it forms a straight line. The same goes for the sum of angle 3 and 4.
Since we are given the measure of angle 2, we can find the measure of angle 1 by subtracting 143° from 180°.
180°-143° = 37°
We know that the intersecting lines form 2 sets of vertical angles, which are congruent. This means that the angles opposite from each other have the same measure. Therefore, both angle 2 & 4 have a measure of 143°, while angle 1 & 3 have a measure of 37°.
Answer:6,000
Step-by-step explanation:
Mrs. Smith donated $20
The constant proportionality is $1 because no matter what, Mrs. smith will donate $1 for each mile. So if Sam were to only walk 1 mile, mrs. smith would donate $1. Or seen as a 1:1 proportion.
Answer:
Total= 7896 points
Step-by-step explanation:
Method 1: 658 x12 = 7896 (in most cases you'd simply use a calculator to instantly solve or could use the 2 stepped multiplication method)
Method 2: 658x10= 6580 658x2=1316
therefore, 6580+1316=7896 ( this method is extremely useful for certain values since its simpler)
