Answer:
Option C. 
Step-by-step explanation:
we know that
In the right triangle ABC
The tangent of angle B is equal to the opposite side angle B divided by the adjacent side angle B

substitute the values

Answer:
Step-by-step explanation:
(-3/4)x + 9 = (-1/2)x + 8
9 - 8 = (-1/2)x + (3/4)x
1 = (1/4)x
x = 4
y = (-3/4)4 + 9
y = -3 + 9
y = 6
Answer:
7,7
Step-by-step explanation:
Possibly 7,7 becuase p+q=pq, therefor 2,1+5,6=7,7
<span>The correct answer is The original height of the plant was 4 mm.</span>
Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
