Find the measure of Angle 1.

Mathematics
1 answer:
BartSMP [9]2 years ago
3 0

Answer:

85°

Step-by-step explanation:

  • Angles in a triangle add up to 180°.
  • 40° + 55° = 95° - This means that there is already 95° in the triangle
  • To find the missing angle (angle 1) we need to do 180 - 95 which is 85°.

Hope this helps!

Tpy6a [65]

Answer: 3/16 gallons of water

Step-by-step explanation:

With any fraction, if you multiply it by its reciprocal, it equals 1.  (ex: 3/4*4/3=1, 1/2*2/1=1, 71/256*256/71=1)  Thus, 2/3*3/2=1.  Because 2/3 of the bin=1/8 gallon, simply multiply both sides of the equation by 3/2 and you will get that 1 bin of water=0.1875 gallons of water, or 3/16 gallons of water.

Hope it helps <3

I'M OFFERING 20 POINTS-
Dafna11 [192]

Answer:

Third option is correct. Scale factor 3 ; enlargement.

Step-by-step explanation:

It is given that the figure A'B'C'D' is a dilation of figure ABCD.

We know that after dilation the corresponding sides of image and preimage are in the same proportion.

The image of AD is A'D'.

From the figure it is noticed that the A(-1,2), D(-1,-1), A'(-3,6) and D'(-3,-3).

Distance formula is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

AD=\sqrt{(-1+1)^2+(-1-2)^2}=\sqrt{9}=3

A'D'=\sqrt{(-3+3)^2+(-3-6)^2}=\sqrt{81}=9

Scale factor is constant which represents the relation between image and preimage.

k=\frac{A'D'}{AD}

k=\frac{9}{3}

k=3

Therefore the scale factor is 3.

If k>0 it means enlargement and if k<0 it means reduction. Therefore third option is correct.

What is the area of the composite figure?
mars1129 [50]

Answer:

34.9^2

Step-by-step explanation:

Well if one side is 4 cm then the square is 16cm^2.

The area of a circle is pi r^2.

So the radius is 2.

we plug 2 in.

pi 4

12.6/2

6.3

6.3 * 3 = 18.9cm^2

18.9 + 16 = 34.9
