Answer:
I'm not sure if this is correct, but if I'm not mistaken, it should be 26.4 multiplied by 3/7.
Step-by-step explanation:
The reasoning is actually pretty simple. First, find the distance between points F and B. (Hint: Use the Pythagorean Theorem) Then, take that distance, and multiply is by 3/7. Okay, 11.314. That means that the next point should be about 11.314 away from point F, and on the line between those points. Good Luck! I think you can figure out the rest.
Answer:
∠ A = 140° , ∠ B = 30° , ∠ C = 10°
Step-by-step explanation:
the sum of the 3 interior angles = 180°
sum the given angles and equate to 180
x - 5 + 2x + 140 = 180
3x + 135 = 180 ( subtract 135 from both sides )
3x = 45 ( divide both sides by 3 )
x = 15
then
∠ A = 140°
∠ B = 2x = 2 × 15 = 30°
∠ C = x - 5 = 15 - 5 = 10°

Answer:
yes
Step-by-step explanation:
The triangles are given as right triangles. Hypotenuses QT and RS are given as congruent.
We also have XS ≅ TP. By the addition property of equality, this means ...
XS +ST ≅ ST +TP
By the segment sum theorem, this means ...
XT ≅ SP
XT and SP are the corresponding legs of the right triangles. So, we have corresponding hypotenuses and corresponding legs congruent. This lets us conclude ΔXQT ≅ ΔPRS by the HL theorem.
