Answer:
A quadrilateral's interior angles have a sum of 360°.
Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.
We can add these angles plus the unknown angle to equal a total of 360°.
85 + 100 + 90 + x(our unknown missing angle) = 360
simplify
275 + x = 360
Isolate x by subtract 275 from both sides;
-275 -275
x = 85, ∠1 = 85°
We can also double check:-
85 + 100 + 90 + <u>85</u> = 360
360 = 360 which is correct.
Answer:
Well X=8 in standard form is NaN or 8 * 10 to the power of 0
Answer:
12 if im correct
Step-by-step explanation:
first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time
first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125
giving us 11.84
since it is time, 11 hrs would be too little of a time so we need to round up to 12
Hope thats right
