Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
Answer: 3
Step-by-step explanation: i don't know how it explain it
Answer:
8/12 yard or 2/3 yard
Step-by-step explanation:
The sum of the two lengths is ...
5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd
This fraction can be reduced by removing a factor of 4 from numerator and denominator.
8/12 yd = 2/3 yd
If the arm portions are end-to-end, the total length is 2/3 yard.
Answer:
The answer is C. or 15 cm
Step-by-step explanation:
50 cm x 15 cm= 750 cm
Multiply 50 centimeters by 15 centimeters to get 750 centimeters
Answer:
x = 35
Step-by-step explanation:
Supplementary angles add up to 180°.
if (3x + 15)° and 60° are supplementary, then
3x + 15 + 60 = 180
now, you just have to solve the equation.
3x + 75 = 180
3x = 105
x = 35
Check
3*35 + 15 + 60 = 180
105 + 15 + 60 = 180
180 = 180
