Answer:
It's QR (option b) which is a congruent part of the figure. You can also figure out if they are same by seeing they both as the longest sides..
Answer:
19. x = 65
20. x = 12
21. x = 35, y = 85
Step-by-step explanation:
19. 2x -10 = 120
2x (-10 + 10) = (120 +10)
2x/2 = 130/2
x = 65
20. 2x + 4x + 108 = 180
6x + (108 - 108) = (180 - 108)
6x/6 = 72/6
x = 12
21. 2x + 25 = 3x - 10
2x + (25 - 25) = 3x (- 10 - 25)
(2x - 3x) = (3x - 3x) - 35
-x/-1 = -35/-1
x = 35
3x - 10 + y = 180
3(35) - 10 + y = 180
105 - 10 + y = 180
(95 - 95) + y = (180 - 95)
y = 85
Sin E= 0. 198.
E= 11.42°
Step-by-step explanation:
using Pythagoras theorem.
Hyp²= base² + height ².
101²= 99²+x²
x²= 101²-99²
x²=10201-9801.
x²=400
x=√400
x=20
sin E = opposite
________
adjacent.
sin E= 20
__
101.
sin E=0.198.
E= sin^-1(0.198)
E= 11.42°
Answer:
y = -1x+1
Step-by-step explanation:
The equation for a line in slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -1x+b
Substitute in the point
0 = -1(1) +b
0 = -1+b
1 = b
The equation is
y = -1x+1

f (x)=4x-x/6
f (x)=23x/6
6.f (x)=23x
x=6.f (x)/23
f^-1 (x)=6.x/23
