Answer:
1)x is 8.5 y is 1.6 b) y= 7.8 x=6.8
Step-by-step explanation:
1) you have to times 3.4 by 2.5 because if you ties 2 b 2.5 is 5. Then you have to do the opposite for y, you have to divide 4 by 2.5.
b) 10.8 / 2 is 5.4 so 15.6/2 is 7.8. 3.4 * 2 is 6.8
I think its this.
Answer: G = 50°, I = 50°, H = 80°
Step-by-step explanation:
First and foremos, the sum of three angles of a triangle is 180°
2x + 2x + (4x - 20) = 180°
8x - 20 = 180°
8x = 180° + 20 (adding 20 on both sides)
8x = 200°
x = 200/8
x = 25
The value of the angles can be found by replacing the value of x with 25
2x = 2 x 25 = 50°
Therefore, the angle of two angles are 50°
And the other is (4 x 25) -20 = 80°
Answer:
h=A-2πr2/2πr
Step-by-step explanation:
3 Divided by 4 is .75
0.75 divided by four is 1/2
1/3 divided bt 4 is 1/12
3/32 + 1/12 is 17/96 (that is in simplest form)
Therefore
17/96
