Answer:
x = 30.
Step-by-step explanation:
For the triangles to be similar corresponding sides must be in the same ratio.
So 50/ 75 = x / 45
75x = 50*45
x = 50* 45/75
= 2 * 45 / 3
= 30. (answer).
Answer:
The measure of the angles in degree is 57.5 degrees
Step-by-step explanation:
If two angles are congruent, they are equal in value
Let the number be x
2x + 3 = 3x-54.5
Thus;
3x-2x = 54.5 + 3
x = 57.5
Answer:
70 units
Step-by-step explanation:
Answer:
x = - 1/45.
Step-by-step explanation:
The area of a Triangle is 1/2BH (B=Base length, H=Height)
When looking at the points, we can figure out the following:
The distance between the two points at the base is 8 (to get from -4 to 4 you must add 8) and the height is 4 (to get from -4 to 0 as well as 0 to 4, the distance is 4).
Now we plug in our values:
Area= 1/2(8)(4)
=1/2(32)
=16 Units squared
Therefore, your answer is 16 units squared.
I hope this Helps!
