3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
The answer is to the problem is 120 °
Answer: A
Step-by-step explanation:
For this problem, we need to understand how translations work.
As you can see, the triangles only slide to the right side, along the x axis. Therefore, we can eliminate B and C.
Now, we can see that the triangle has shifted by +8 units. Therefore, A is the correct answer.
The side length is the square root of the area, so is ...
... √(25/16 ft²) = (√25)/(√16) ft = 5/4 ft
Answer:
acute angle measure less than 90 degrees, right angle measure 90 degrees, Obtuse angle measure more than 90 degrees, straight angle equal to 180 degrees, reflex angle is an angle greater than 180° and less than 360°, complementary angle either of two angles whose sum is 90°, supplementary angle either of two angles whose sum is 180°
