Answer:</h2><h2>
The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10 
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = 
bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 = 
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
The answer is Letter C - 130<span>°

Coterminal Angles are angles that share a common terminal or end position. In finding the coterminal angle, you can add or deduct 360°. In this case, you are asked to get its positive coterminal angle. You will simply add 360° to -230°.
Solution: 360° + -230° = 130°

If
you want to express the vertex form of an equation you have to know
that the vertex form of a parabola’s equation can be expressed as:
y = a(x - h)</span>²<span> + k. The way you know how the parabola will look like
is:
If
a is positive then the parabola opens upwards like a U.
If
a is a negative number, then the graph will open downwards like an
upside down U.

Cross multiply or just multiply both sides by 24
24x/6=36
4x=36
divide both sides by 4
x=9
