Answer:
√2
Step-by-step explanation:
Angle ( θ ) = 45
Hypotenuse side = 2
Opposite side = x
Formula : -
sin θ = Opposite side / Hypotenuse side
Note :
The value of sin 45 = 1/√2
sin 45 = x/2
1/√2 = x/2
Cross multiply,
x*√2 = 2*1
x√2 = 2
2 can be simplified as √2 * √2
x√2 = √2*√2
Divide √2 on both sides,
x = √2
A= 35° because 180°-80°-65°= 35°
b=50° because 180°-95°-35°= 50°
c=85° because 180°-95°= 85°
d=30° because 180°-65°-85°= 30°
For these you just have to remember that the sum of the angles of a triangle is 180°, and the same for a straight line.
Answer:
1. b. 4/7
2. c. 3
Step-by-step explanation:
To find the slope
m = (y2-y1)/(x2-x1)
m= (7-3)/(5 - -2)
= (7-3)/(5+2)
= 4/7
m = (y2-y1)/(x2-x1)
m= (5-2)/(2 - 1)
= 3/1
