Answer:
3): 14
Step-by-step explanation:
The problem states that ABC and DEF are similar. Therefore, dsue to similar triangles, we have 7x/7=4/x, so x^2=4. Therefore, x=2 (because x cannot be negative). Therefore, AB = 7x = 7*2=14
Answer:
9.9cm
Step-by-step explanation:
If side h cm is opposite of 51° and side 8cm is adjacent to 51°, use the tangent function to calculate the opposite side h cm:
tan(51°)=opposite/adjacent=h/8
tan(51°)=h/8
8tan(51°)=h
9.879177252=h
9.9=h
Therefore, the value of h is 9.9cm
Angle AKB is 50°...Angle ACF is 90° cuz if u look at the pic closely it shows the little box
So, this would be a common circle question.
First, 20 degrees from a circle's curcumference would be 20/360, which is 1/18.
This means that the length of the arc of AB should be 1/18 of the circumference.
The formula for the circumference it 2pi*r
2*pi*27=54pi
54pi* 1/18= 6 pi
