In the given figure,
line a & b are parallel, line l and m are parallel.
for line a and b are parallel and line l act as a transversal.
So, angle BAC and ACD are the alterantive interior angles.
Angle BAC = Angle ACD
2x = 46
i.e. Angle BAC = 46
Lines l and m are parallel, a line act as a transversal,
So, the angle BAC and angle y are the corresponding angle,
Since the pair of corresponding angles are always equal so,
Angle BAC = y
46 = y
y = 46
Answer : y = 46
Answer:
30% = 30/100 = 3/10
3 : 10
Step-by-step explanation:
Answer:
<u>Step-by-step explanation:</u>
9x² + 4 = 0
<u> -4 </u> <u>-4 </u>
9x² = -4
x² =
Slope = y2 - y1/x2 - x1
= -3 - (-1)/8 - (-2)
= -3 + 1/ 8 + 2
= -2/ 6
= - 1/3
hope this helps :)
From Pythagorean Identities <span><span><span>sin^2</span>x</span>+<span><span>cos^2</span>x</span>=1</span>
and from that identities we can have <span><span>sinx</span>+<span>cosx</span>=1</span>, taking <span><span>sinx</span>=1−<span>cosx</span></span> and substitute in the equation
<span><span>sinx</span>+<span>cosx</span>=1</span>
<span><span>(1−<span>cosx</span>)</span>+<span>cosx</span>=1</span>
Remove the parenthesis
<span>1−<span>cosx</span>+<span>cosx</span>=1</span>
cancel <span>cosx</span>
<span>1=1</span>
