Angles  ∡DBE ≅ ∡ACD= 3x  reason - angles with parallel arms

Angles ∡ADC and ∡ADB=95° are supplemental angles which means

∡ADC + ∡ADB=180° => ∡ADC = 180° - ∡ADB= 180°-95°= 85°

In the triangle we have ∡ADC + ∡ACD + ∡CAD = 180° =>

85 + 3x + 2x = 180 => 85 + 5x = 180 => 5x= 180-85 => 5x=95

x=95/5 => x=19°

Good luck!!!

Luba_88 [7]
We know that
<span>the garden's perimeter is 112 =[(x+4)+(x+4)+(x+4)+(x+4)]  

112=4*[x+4]------------ > 112/4=x+4
x=(112/4)-4=28-4=24 units

the answer is x=24 units</span>

The ratio of fish to ducks at the water's edge was 5 to 2. If there were 28 in all, how many were fish?
densk [106]

A is in the shape of a quarter circle of a radius of 15cm. B is in the shape of a circle. the area of shape A is 9x the area of
RideAnS [48]

The radius of B is 2.5cm.

<h3>What is a circle?</h3>

A circle is the locus of points equidistant from a common point which is called the center of the circle.

Analysis:

Area of circle A = πr^{2}/4 = π(15)^{2}/4 = 225π/4

Area of circle B = πr^{2}

But A = 9B

225π/4 = 9 x πr^{2}

r^{2} = 225/36 = 25/4

r = \sqrt{\frac{25}{4} } = 5/2 = 2.5cm

Carl is going to make a frame for a picture. The dimensions of the frame need to be 2 feet by 18 inches. How long must the board
kenny6666 [7]


<span>A rectangle has two pairs of sides of equal length. </span>

<span>So perimeter P = 2ft + 18in + 2ft + 18in </span>

<span>The units have to be all the same to add them so.... </span>

<span>P = 2ft + 1.5ft + 2ft + 1.5 ft </span>

<span>P = 7 ft. </span>

<span>So the board would have to be 7 feet to make a 2ft x 1.5ft picture frame.</span>
