A tangent line creates a 90 degree angle with a radius line that touches the tangent Line.

Line BC is a radius that touches the tangent line at point C

The angle created is 90 degrees.

The answer is C. 90 degrees.

bulgar [2K]

Turn the fraction into a improper fraction.

4 5/6 -> 29/6

Divide both numbers.

29 / 6 = 4.833...

Best of Luck!

Please need help for question number 26

(8,12)(14,3)

Use midpoint formula

(X1+x2/2, y1+y2/2)

Substitute with your points

(8+14/2, 12+3/2)

Solve each

(22/2,15/2)

Cancel common factor 2

(2×(4+7)/2(1),15/2)

Simplify

(4+7/1,15/2)

This is your midpoint

(11, 15/2)

29. Find the height of the trapezoid. Use this height to find the area. (A =

harkovskaia [24]

Answer:

The area of the trapezium is 168

Step-by-step explanation:

Area of a Trapezoid

Given a trapezoid of parallel bases b1 and b2, and height h, the area is calculated with the formula:

$\displaystyle A=\frac{b_1+b_2}{2}h$

The trapezoid in the figure has b1=15 and b2=27. We need to find the height. If we focus on triangle BCD, we can calculate the height as the distance EC by using the Pythagora's Theorem:

$10^2=EC^2+BC^2$
