Asurveyor measures the lengths of the sides of a triangular plot of land. what is the measure of the angle of the triangular plot at which the surveyor stands? approximate to the nearest degree.
cos–1(0.75) = 41°
cos–1(0.125) = 83°
cos–1(0.15) = 89°

Second option is correct.

Step-by-step explanation:

Since we have given that

a = 300 m

b = 250 m

c = 200 m

We need to find the measure of angle i.e. A

As we know the "Law of Cosine rules ":

Hence, Second option is correct.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

where are the options?
