A right triangle has to have 1 90 degree angle
All angles inside a triangle must add up to 180 degrees
90 + 38 = 128
180 - 128 = 52
answer is C<span />
Answer:
1-cos2A/sin2A
=(1-cos^2 A+sin^2 A)/(2sinAcosA)
=(sin^2 A+sin^2A)/2sinAcosA
=2sin^2 A/2sinAcos^2 A
=sinA/cosA
=tanA
Answer:
(2x-1)/2x
Step-by-step explanation:
Given the function 1-(1/x÷2)
Using the rule of BODMAS
Solving the equation in bracket first, will give;
1/x÷2
= 1/x×1/2
= 1/2x
The equation then becomes
1-1/2x
Next is to look for the LCM of the resulting equation
1-1/2x
= (2x-1)/2x
The expression equivalent to the fraction is (2x-1)/2x

-10x+y=4
u just need to plug in values of x in function to get y values
x=-2
-10(-2)+y=4
20+y=4
y=-16
-10x+y=4
x=-1
-10(-1)+y=4
10+y=4
y=-6
-10x+y=4
at x=0
-10(0)+y=4
y=4
u are getting y values according to x values
y=-16 at x=-2
y=-6 at x= -1
y=4 at x=0
next u can find
