The other expression that has a value of 
is A) sin B.
Step-by-step explanation:
Step 1:
For angle B, the opposite side measures 7 units, the adjacent side measures 24 units and the hypotenuse measures 25 units.
Step 2:
For angle A, the opposite side measures 24 units, the adjacent side measures 7 units and the hypotenuse measures 25 units.
Step 3:
tan C cannot be determined as C is the right angle. The opposite side and hypotenuse of the triangle would be the same.
So sin B also has a value of 
This is option A.
Parallelogram !
I think so
Answer:
y = 4
x = -1
Step-by-step explanation:
4x + 2y = 4 Eq. 1
3x - y = -7 Eq. 2
from the Eq. 2
3x = y - 7
3x + 7 = y Eq. 3
Replacing the value of the Eq. 3 in the Eq. 1
4x + 2(3x+7) = 4
4x + (2*3x + 2*7) = 4
4x + (6x + 14) = 4
10x + 14 = 4
10x = 4 - 14
10x = - 10
x = -10/10
x = -1
from the Eq. 3
3x + 7 = y
3*-1 + 7 = y
-3 + 7 = y
4 = y
Check:
from the Eq. 1
4x + 2y = 4
4*-1 + 2*4 = 4
-4 + 8 = 4
Answer:
45 square centimeters
Step-by-step explanation:
to find the area of the rectangel multiply its height, which is 5 by its length which is 9.
9 x 5 = 45
