Iam in urgent need of some so me a quadrilateral has angles that measure 72 degrees, 98 degrees and 65 degrees what is the measure of the fourth angle? ?

So I could be completely wrong, or I could be completely right, but quadrilaterals interior angles equal 360 degrees.

So, if you ad up 98, 72, and 65 you end up with 235 degrees.

In order to find the fourth angle, you would just subtract 235 from 360 and get 125 degrees.

BUT, maybe see if someone else answers too, because I am not 100% sure.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
