All angles add up to 180 and you know you have a right angle which is 90 degree. So 180-90=90 90/2=45

Since the sum of the interior angles of a triangle equals 180° and one of the angles is a right angle (90°), the sum of the remaining two angles must equal 90° (180°-90°=90°)

Answer:

a) CP = SP/1.1

b) CP = $59.50

c) GST = $5.95

Step-by-step explanation:

a) Divide by the coefficient of CP.

SP = 1.1×CP

CP = SP/1.1

b) Use the formula with the given value.

CP = $65.45/1.1 = $59.50

c) You can do this two ways: subtract CP from SP, or multiply CP by 0.1.

GST = SP -CP = $65.45 -59.50 = $5.95

GST = CP×0.10 = $59.50 × 0.10 = $5.95

Find the value of x, rounded to the nearest tenth <br> A. 24.5<br> B. 18<br> C. 16.1<br> D. 2

Strike441 [17]

Answer:

B. 18

Step-by-step explanation:

Given:

There are two chord in the circle.

These chords are divided in two segments.

Segments of 1 chord is 21 and 6.

Segments of 2 chord is x and 7.

Now by using Intersecting Chord Theorem which states,

"When two chords intersect each other inside a circle, the products of their segments are equal."

Hence from above theorem we can say that;

$x\times7=21\times6\\7x = 126\\x= \frac{126}{7}\\x=18$

Hence the Value of x is 18.
