Need help with this I'm so confused :(:(​

Mathematics
1 answer:
leonid [27]3 years ago
7 0

Step-by-step explanation:

We know that m∠1 is 110°. If we look at m∠7 closely, we can see that while m∠1 is an obtuse angle (greater than 90° but less than 180°), m∠7 is an acute angle (less than 90°).

Now, we can eliminate 110° and 180° since we know that m∠7 is an acute angle. There are only 2 choices now: 40° or 70°.

If you flip the image around, you can see that the angle is slightly less than 90°, so it has to be 70°.

Answer:

2) 70°

What is the value if x ?
dexar [7]

Answer:

x=3

Step-by-step explanation:

We have to use the fact that all angles of a triangle add up to 180 and two supplementary angles add up to 180.

First,QRS forms a line, so angle QRT and angle TRS add up to 180 or, if we call angle TRS y for the sake of having it as a variable, 45x+y=180 or y=180-45x

Now we have all three angles of the triangle, and we know all three add up to 180, so startign with our newly found angle, (180-45x)+(25x)+(57+x)=180

180-45x+25x+57+x=180

237 - 19x = 180

57 = 19x

x=3

Let me know if you need any further explanation.

Giving the following information:

Purchase price= $2,816

Discount rate= 12% = 0.12
