Answer:
∠S = 19°
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we must first find how much is left.
<em>180 - 142 = 38</em>
And since we know that the two lines are congruent, we know that the two other angles will be the same. So we divide the remaining by 2
<em>38 ÷ 2 = 19</em>
So both other angles are 19° meaning that ∠S is 19°

F(x) = cos x
f'(x) = -sin x
f''(x) = -cos x
f'''(x) = sin x
f''''(x) = cos x
90/4 = 22 Remainder 2
Therefore, 90th derivative of f(x) = cos x is -cos x.
Answer:
The answer is -0.25.
Step-by-step explanation:
Using PEMDAS, add 9.5 + 11 first, which results in 20.5. Then substract 20.5 from 20.25, 20.25 - 20.5. This leads to -0.25 or -1/4.
None of them will get into a negative number. When you have like "2x" is the number twice, right? Some number has to be negative
Trigonometric values (sin, cos, tan etc.), represents the ratio between two sides.
In this case the triangle is dilated, which means the size will change but the shape will stay proportional.
Because the sides grew proportional their ratio stays the same; so, the tan in the second triangle is 22/5 too.
Moreover, because the sides grew/shrunk proportional, the angles stay the same.
Because same angles have the same trigonometric values, tan(x) in second triangle becomes 22/5.
