The answer is A. 35 degrees

Step-by-step explanation:

The triangle has to measure up to 180 degrees

105 + 40 = 145

Subtract the total from 180

180-145= 35

the missing angle is 35

Check Answer:

to check your answer add up all the angle measurements

your total should add up to 180

35 + 40 + 105 = 180

Mariulka [41]

= 187.3 yards

Step-by-step explanation:

The set-up will represent a triangle whereby the :

Width = Height = 150 yards
Diagonal = Hypotenuse = 240 yards
Length = Base = ?

${a}^{2} = {c}^{2} - {b}^{2} \\ {a}^{2} = {240}^{2} - {150}^{2} \\ {a}^{2} = 57600 - 22500 \\ \sqrt{ {a}^{2} } = \sqrt{35100} \\ a = 187.3yards \: (rounded \: off \: to \: 1dp)$
