Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
Answer:
The area of the rectangle is 40 and the area is the triangle is 20 therefore, the area of the shape is 60
Step-by-step explanation:
Rectangle:
8cm x 5cm = 40cm
Triangle <em>(</em><em>1</em><em>/</em><em>2bxh</em><em>)</em>
The base of the triangle would be 8 cm as the top and the bottom of the rectangle is the same width. The height was given to be 5 cm (<em>note the height is the dotted line</em>) Therefore the area of the triangle is half the base which is (8×1/2 = 4) times the height (5); which is 20.
Area of parallelogram
= L × H
= 23 × 13
= 299 feet²
Answer:
The equation of the graph is y=x-20
Step-by-step explanation:
10.65/8.20= 1.30
1.30-1 ( for the 100% that was there)
.30 x100 (to get in percent)= 30 percent increase
