Answer:
This is a weird one but d=443/24
Step-by-step explanation:
General formula for area of triangle is 
.
Where:
is height of triangle perpendicular to base side of triangle.
is the length of base side of triangle.
Multiplying and results in rectangle, dividing that by 2 gives you area of a triangle.
Hope this helps.
Answer:
The distance between (-9, 8) and (-3, -1) will be:
units
Step-by-step explanation:
Given the points
Finding the distance between (-9, 8) and (-3, -1)
units
Therefore, the distance between (-9, 8) and (-3, -1) will be:
units
1+8=3r
9=3r
Both divided by 3
3=r
Answer:
x=54
Step-by-step explanation:
these two angles are supplementary to each other. this is because alternate interior angles are congruent, and 2x+42 degrees is supplementary to the alternate interior angle of x-24 degrees. so, we can add these two numbers up and set it equal to 180.
2x+42+x-24=180
3x+18=180
3x=162
x=54
if this question is asking for x, 54 is the answer. if it is asking for the angle measures, plug in 54 for x for each angle and solve.
