3x1=3
6x2=12
12+3=15
the anser is 15
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°
1. ABC and ADE are similar triangles because because its measures are proportional
2. x=4 because AD is twice AB
3. AE is twice the size of AC
0.000044, because 10 to the negative fith is 0.00001, and 0.0001 times 4.4 is 0.000044
