Answer:

EBC and CBF are supplementary.

EBD=66

Step-by-step explanation:

Since vertical angles are congruent, ABE=CBF

ABE=40-x

40-x + 6x-30=90

5x+10=90

5x=80

x=16

16(6)-30=66

We have seen that isosceles triangles have two sides of equal length. The angles opposite these sides have the same measure. Use

dedylja [7]

angle 1 = 180° - 115° (Linear Pair)

angle 1 = 65°

angle 2 = angle 1 = 65° ( Angles on the equal sides of an isosceles triangle )

angle 3 = 180° - (65° + 65°) (Angle Sum Property)

angle 3 = 180° - 130°

angle 3 = 50°

angle 4 = 180° - 65° (Linear Pair)

angle 4 = 115°

angle 5 = 115° (Vertically Opposite Angles)

Answer:

Step-by-step explanation:

Each colored section is 27 small squares, so is 27/100 = 0.27 of the whole. There are 9 colored sections, together totalling 2 wholes plus 43 small squares, or 2.43.

The equation this represents could be ...

0.27 × 9 = 2.43 . . . . . matches choice C

A ball of radius 13 has a round hole of radius 9 drilled through its center.

GREYUIT [131]

Answer:

Step-by-step explanation:

Given

radius of sphere $R=13\ units$

Hole is drilled with radius $r=9\ units$

Now this drilled hole will be in the form of Cylinder with height equals to diameter of sphere thus

Volume of drilled hole is

$V_d=\pi \cdot r^2\cdot h$

$V_d=\pi \cdot (9)^2\cdot 26$

$V_d=2106\pi$

Volume of Sphere

$V_s=\frac{4}{3}\pi R^3$

$V_s=\frac{4}{3}\pi (13)^3$

$V_s=2929.33\pi$

Remaining volume $V_{remaining}=2929.33\pi -2106\pi =823.33\pi$

$V_{remaining}=2586.90\ units^3$
