Answer:
1 = 52°
2=79°
3= 38°
Step-by-step explanation:
each triangle equals 180°
and 1 and 3 also make a right angle which should always be 90°
Answer:
5
Step-by-step explanation:
Convert the element to fraction:
/
Switch the division to multipl:
2/1 * 2/5
Cross multiply:
2 is elimiated and 1 and 5 remain.
Answer is 1/5 which is 5.
I don't know exactly what a fraction box is sorry
Answer: x=7, y=-2
umm do you need to show work?
<span>Differentiate implicitly:
</span>
<span>
Solve for y
</span>
<span>When the tangent is parallel to the x-axis we have y'=0, so we must solve
</span>
<span>To find the actual value of x we plug this expression for y into the original equation
</span>
<span>Plugging this into the formula for y above gives the points
</span>
<span>which is where our tangent will be parallel to the x-axis.</span>
