Question

in the following figure triangle ABC is congruent to triangle pqr and angle C is equal to angle R is equal to 30 degree angle b is equal to angle Q is equal to 50 degree BC is equal to QR is equal to 5.2 now we can find that angle is equal to
​

Answer 1

Answer:

Done!

Step-by-step explanation:

We will need to find the sides

angle P = 180 - 60 - 75 = 45°

let PQ=x , QR = y , PR = z

x/sin75 = y/sin45 = z/sin60

let's assign an arbitrary value of y = 1 to our smallest side

using x/sin75 = 1/sin45

we get x = .1.366025

using 1/sin45 = z/sin60

z = 1.224745

so sum of those sides

= 1 + 1.366025+1.224745

= 3.59077

but we want this sum to be 12, so each of our sides must be multiplied by a factor of 12/3.59077 = 3.3419

giving me sides of

x = 4.565122

y = 3.3419

z = 4.09298
