Since x = 10, you can plug in 10 for "x" in the equation
5(7x + 5)
5(7(10) + 5)
5(70 + 5)
5(75)
375
Answer:
9°
Step-by-step explanation:
You can make use of any of the trigonometric ratios to determine N, or you can let your calculator tell you what it is by solving the triangle.
SOH CAH TOA reminds you that
... sin(N) = 13/85 . . . . N = arcsin(13/85)
... cos(N) = 84/85 . . . N = arccos(84/85)
... tan(N) = 13/84 . . . . N = arctan(13/84)
all will tell you N ≈ 8.79741° ≈ 9°
_____
If you use inverse functions on your calculator, be sure it is in <em>degrees mode</em>.
Answer:
10,
Step-by-step explanation:
The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.
The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200
y = √200 = √100√2=10√2
Answer:
Step-by-step explanation:
Y=3x-4
Slope of this line = 3
Slope of the line parallel to this line = 3 {slope of parallel lines are equal}
Slope of the line perpendicular to this line = -1/3 {product of the slope of perpendicular lines= -1}
Answer:
Rs. 2970 is the interest
Step-by-step explanation:
30 months is same as 30/12 = 2.5 months
I = PRT/100
P is 18000
R is 6.6%
T is 2.5 years
Substitute all these
I = (18,000 * 2.5 * 6.6)/100
= 2970
