x = 30
Step-by-step explanation:
Answer:
Option C. cos70°
Step-by-step explanation:
we know that
If two angles are complementary, then the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle
Remember that
Tow angles are complementary , if the sum of their angles is equal to 90 degrees
so
If A+B=90°
then
sin(A)=cos(B)
cos(A)=sin(B)
In this problem we have
A=20°
B=90°-20°=70°
therefore
sin(20°)=cos(70°)
cos(20°)=sin(70°)
Your question has been heard loud and clear.
This is a right triangle , which means it has a hypotenuse ( longest side of the triangle)
X is the length of the hypotenuse. We need to find x.
By Pythagoras theorem ,
Side^2+side^2= Hypotenuse^2
2.5^2+3^2= x^2
= 6.25+9=x^2
15.25=x^2
So , x = root of 15.25 = 3.9
Therefore , x= 3.9
Thank you
Answer:
The slope is 1
Step-by-step explanation:
for every 1 unit crossed in the X value, 1 is crossed the Y value, which is
1/1 or 1
