This triangle is classified as a right triangle because it contains one right angle (90 degrees).
An obtuse triangle is given that classification when one of the angles is greater than 90 degrees.
An acute triangle is any triangle that has all 3 angles less than 90 degrees.
I'm assuming the integral is

We have

Then substituting
and
, the integral transforms and reduces to

which we can rewrite as

and so

Answer : A
The word "increased" indicates a plus sign. The word "is equal" helps show us show that something is = to 15
Answer:
26.8°
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.
If cos B = 0.8926
then arc cosine 0.8926 which may be expressed as cos-1 0.8926 will give the value of B.
B = cos-1 0.8926
= 26.8°
Given:
The graph of line.
To find:
The gradient of the line using rise/run method.
Solution:
We know that the gradient of a line is also known as slope.

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.


Now,


The gradient of the line is
.
Therefore, the correct option is C.
