length is 8 width is 7 for the area of the rectangle
Answer:
Step-by-step explanation:
Since it is an equilaterla triangle, we can see the side opposite to that of side length 4 is 60 degrees. Since the other angle is a right angle (90 degrees), we can find that the other side is 30 degrees (the degrees add up to 180). We can also see that this is a 30-60-90. We can see that the side x, through the identity (you can find 30-60-90 identity online), we see that the side x is . However, it is also asking us to simplify this, so we multiply the top and bottom by and get
Answer:
3,8,15
Step-by-step explanation:
Answer:
C. 69°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
two of the angles are given to find the third one we subtract their sum from 180
180 - (36+75) = 69 degrees
Step-by-step explanation:
are 1 and 3, then their sum is 4 which is divisible by 4.
are 3 and 5, their sum is 8 which is divisible by 4.
