Answer:
If angle 2 = 110 then angle 4 = 110
360 = 110 + 110 + x
Angle 1 + Angle 3 = 140
Since vertical angles are equal, then Angle 1 = 140 / 2 = 70 degrees

Answer:
a) 74.3
b) 98.8
Step-by-step explanation:
The tenth decimal place is the first place immediately to the right of the decimal point. When rounding, you first need to look at the number to the right of the place you wish to find. If the number in this spot is 5 - 9, round the number in the tenth decimal place up one unit. If the number is 0 - 4, keep the number in the tenth decimal place the same. Finally, remove all of the numbers to the right of the tenth decimal place.
a) 74.3472
^ tenth
The next number to the right (4) is not big enough to round up
a) 74.3
b) 98.759
^ tenth
The next number to the right (5) is big enough to round up
b) 98.8
I used the substitution method and got (2,6) and (-1,3)
Answer:
b=−1/14ot+2
Step-by-step explanation:
Let's solve for b.
to−8+5b=−6+26−9b
Step 1: Add 9b to both sides.
ot+5b−8+9b=−9b+20+9b
ot+14b−8=20
Step 2: Add -ot to both sides.
ot+14b−8+−ot=20+−ot
14b−8=−ot+20
Step 3: Add 8 to both sides.
14b−8+8=−ot+20+8
14b=−ot+28
Step 4: Divide both sides by 14.
14b

=
−ot+28
