Answer:
Letters as in the attached image.
Triangles ABC and ADC are congruent by SSS. From that, corresponding angles are congruent, in parcicualre B and D, both measuring 94°.
Final angle is obtained by difference. The internal angles of a quadrilater add to 360, so the remaining is 360-90-94-94 =82°
2x - 11 >_ 5
To solve for x, we need to get 2x by itself and then simplify.
Add 11 to both sides.
2x >_ 16
Divide both sides by 2 to get x.
x >_ 8 is your solution.
I hope this helps!

Answer:
The answer to your question is 90 cm, 150 cm, 210 cm
Step-by-step explanation:
Data
Proportion 3 : 5 : 7
Perimeter 450 cm
Process
1.- Sum the proportions to find the total number of parts.
3 + 5 + 7 = 15 parts
2.- Divide the perimeter by the total number of parts
450 / 15 = 30
3.- Find the measure of the sides multiplying each ratio by the previous result
Side 1 = 3(30) = 90 cm
Side 2 = 5(30) = 150 cm
Side 3 = 7(30) = 210 cm
