Answer:
relationship between base and hypotenuse is given by cos angle
let angle be ø
cos ø=b/h
cosø=28/34
ø=cos-¹(28/34)=34.5°
Answer:
y=-9x-4
Step-by-step explanation:
Perpendicular lines meet the following condition:
m2*m1= -1 (a)
where m is the slope of a line
m1 is given through equation of line 1, y =1/9 x+2
m2 must be -9 -> from eq. (a)
The Line has the following equation: y=mx+b, where m=-9 and the b is the interception with y axis.
Evaluating the above equation in (-1,5) we have the following equation
5= -9*(-1)+b, we have b=-4
The line has the following equation
y=-9x-4
Slope intercept form
Answer:
The surface area of cone = 54π cm²
Step-by-step explanation:
Given ;
Radius = 3 cm
slant height = 15cm
The surface area of cone = πr ( r + l )
=> π × 3 ( 3 + 15)
=> π × 3 ( 18)
=> 54 π cm²
The answer may be 36 but I am not very sure
