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:
a = 33ft
b= 66ft
c = 48 ft
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- a (shortest side)= a
- b (second side)=2a (twice the length of the shortest side)
- c (third side)= a+15 ( 15 feet more than the length of the shortest side)
Since:
Perimeter = a+b+c
Replacing with the values given:
147 = a+2a+(a+15)
147 = a+2a+a+15
147-15 = a+2a+a
132 = 4a
132/4 = a
33 ft= a
Substituting a =33 in the other expressions:
b=2a = 2(33) = 66 ft
c= a+15 = 33+15 = 48 ft
