Answer:
y=15
Step-by-step explanation:
y-7=8
Add 7 to each side to cancel out the 7 next to the variable.
You get y=15.
Answer:




Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, so angles (2) and (3) are equal 90°.
To find angle (1), we can use the sum of internal angles in the left triangle with angles 52°, (1), and (2):



The diagonals of a rhombus bisects the angles, to the angle next to the angle of 52° is also 52°, then, in the upper triangle, we have:


Answer:
y = 1/2x + 8
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - 10 / 2 - 4
-1 / -2
= 1/2
y = 1/2x + b
10 = 1/2(4) + b
10 = 2 + b
8 = b
