Answer:
∠?=40°
Step-by-step explanation:
Remember that in a line AND a triangle there are <u>180 degree</u>s.
You correctly found the third angle in the left triangle to be 69°, Now plug it into the equation for a line, including 71°:
<u>69°+71°+x=180°</u>
1) Combine the degrees:
140°+x=180°
2) Subtract 140° from both sides:
x=40°
We have now found the bottom left angle for the triangle on the right to be 40°
To find the angle labeled "?" You must plug in all of the known angles of the triangle to be equal to 180°:
40°+100°+x=180°
1) Combine the degrees:
140°+x=180°
2) Subtract 140 from both sides:
∠?=40°
Answer: A − 9/7
Step-by-step explanation:
Hi, to answer this question we have to convert all the numbers into decimal form.
-3 1/3 = - (3x3+1)/3 =-10/3 = - 3.3334
-4/5 = -0.8
Since he number must greater than −3 1/3 but less than − 4/5.
−3 1/3 < x < − 4/5.
- 3.3334 < x < -0.8
The correct option is A = -9/7 , because in decimal form is equal to -1.28-
- 3.3334 < -1.28 < -0.8
