Answer:
11) tan(7x+3) = OE/OJ
7x+3=arctan(OE/OJ)=45
x=6
12) a) x = 40
<ajq = <acq (base angles of isosceles triangle)
50+x+90=180
x=40
b) they are congruent triangle, reason HL (hypotenuse, leg)
aj=ac
aq=qa
right angle equal
Answer:
p>-1 or p<-19
Step-by-step explanation:
4p-10<6p-8 (add 10 to each side)
4p< 6p+2 (subtract 6p from each side)
-2p<2 (divide by -2 and switch the sign)
p>-1
10p+16<9p-3 (subtract 16 from each side)
10p<9p+-19 (subtract 9p from each side)
p<-19

Answer:
81 pi cm^2
or approximately 254.34 cm^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (9)^2
A = 81 pi
Using 3.14 as an approximation for pi
A = 81 (3.14)
A =254.34 cm^2
