Answer:
1) 46.6
Step-by-step explanation:
Given Data:
s1 of Triangle ABC= 4cm
s2 of Triangle ABC=6cm
s3 of Triangle ABC=8cm
As per the side-side-side SSS of a given triangle
the corresponding angles are found by the following law of cosine formula
cos A = (b2 + c2 − a2) / 2bc
Putting the values we get
cos A= (4^2+8^2-6^2)/2(4)(8)
cos A= (16+64-36)/64
A=cos^-0.6875
A=46.57!
Still need help? Let me know
THE ANSWER WOULD BE 5.5
EXPLANATION: AB IS 2.5 and DC IS 8
2.5 - 8 = 5.5
Answer:
27 years
Step-by-step explanation:
P is measured in thosands therefore, P will have a value of 120
so it would be...
120=80e^0.015t
80e^0.015t=120
e^0.015t=120/80=3/2=1.5
e^0.015t=1.5
0.015t= In(1.5)
t=In(1.5)/0.015
∴ t≈27.03 round it to 27 years
It would be greatly appreciated if you gave me the brainlest
