Answer: 22.8 ft. squared
Step-by-step explanation:
5.7 x 8 = 45.6 ÷ 2 = 22.8
area of a triangle = base x height ÷ 2
Step-by-step explanation:
angles on a straight line
Okay since x= -6, we have to plug it in everywhere it says x.
-6^2-6/-6-4
30/-10
The answer to this is -3 .
1st find the slope m.
m= (rise)/(run). Look up the graph and notice that the rise is 1 for a run =5
Then the slope will be 1/5
2 lines are parallel if they have the same slope so it's either
y= 1/5 x + 4 or 1/5 x + 12/5
our function is y = mx + b, but we know that m = 1/5
so the equation is y = 1/5 x + b
and we know that the function passes through the point (-2,2)
To calculate b, plug in y= 1/5 x + b , x & y by their respective values:
2 = (1/5) (- 2) + b
2 = - 2/5 + b and b = 12/5, then the equation is Y= 1/5 X + 12/5
Answer: 110 degrees
Since the 2 unknown angles in the triangle are equal you do (180-40)/2 to find what they are equal to. (It's equal to 70) Now that you have the answer for the two angles, now you can subtract 70 from 180 which gives you 110 degrees and that's your answer
Hope this helped you!
