Answer:

8/21

Step-by-step explanation:

Use the method called KCF, or Keep, Change and Flip for this question.

For this question, keep the first fraction of the equation the same, but flip the 2nd fraction of the denominator and the numerator. For example, you need to change it from 3/4 to 4/3.

So it's 2/7 x 4/3 = 8/21

Hello, happy Friday, I am just here with some geometry questions.
stealth61 [152]

Answer:

m<D = 105

Step-by-step explanation:

So, Triangle STU and DEF are similar triangles, because their corresponding side lengths have the same ratio.

For example FD can be multiplied by 2.5 to get SU, and EF can be multiplied by 2.5 to get TU, and ED can me multiplied by 2.5 to get 15.

Anyways, since the two triangles are similar, they have the same angle measures, meaning that angle D can be found by subtracting 46 and 25 from 180 degrees to find the missing angle, which is 105 degrees. I hope that helps.

Answer:

see explanation

Step-by-step explanation:

The largest angle is opposite the largest side and the smallest angle is opposite the shortest side.

Δ FUN

largest angle is ∠ FUN ( opposite FN )

smallest angle is ∠ NFU ( opposite NU )

Δ GEO

largest angle is ∠ GEO ( opposite GO )

smallest angle is ∠ GOE ( opposite GE )

---------------------------------------------------------------------------

The longest side is opposite the largest angle and the shortest side is opposite the smallest angle.

∠ RTY = 180° - (70 + 55)° = 180° - 125° = 55°

Δ TRY is therefore isosceles with 2 congruent legs RT, RY

longest side is TY ( opposite 70° )

shortest sides are RT , RY ( opposite 55° )
