opposite sides and diagonals of a parallelogram are equal
+ diagonals of a parallelogram meet eachother in the middle so:
10x+14=x+77
10x-x=77-14
9x=63
x=63÷9
x= 7
y+8=4y-19
y-4y=-19-8
-3y=-27
y=-27÷-3
y=9
2z+3=37
2z=37-3
2z=34
z=34÷2
z=17
It’s b. :) hope this helps you
C
hope this helps! good luck. :)
Step-by-step explanation:
m and n are both located on the number line and are on the left of 0.
Therefore m and n are both negative reals.
m¹³ * n⁵
= (-)¹³ * (-)⁵
= (-) * (-)
= (+)
The answer is positive.
Find the adjacent side of the triangle ...
7² + x² = 25²
x² = 25² - 7²
x² = 576
x = 24
The adjacent side of the triangle is 24
Given that sin A =
Since sin A =
We can conclude that o = 7 and h = 25
cos A =
cos A =
