Answer:
E. 12 m
Step-by-step explanation:
b = 2×A/h
= 2×78/13
= 156/13
= 12 m
X=4 you have to write it out as 6x+8=32 the subtract 8 from both sides so it will say 6x=24 then divide 6x and 24 (both sides) by 6 and it is x=4
This is the commutative property of addition
This property is the idea of adding any two numbers in any order you want. For example: 2+3 = 3+2 = 5
In this problem, we have 2.5+12.66 the same as 12.66+2.5
Answer:
3
Step-by-step explanation:
1+3 equals 4, 4 times 2 is 8, 8-10 is -2, -2 divided by 2 is 3
Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
