Answer:

Step-by-step explanation:
Using the given measurements of the angles and the lengths of the sides, we can determine that this figure must be a <u>rectangle</u>.
Diagonals of a rectangle are <em>always</em> equivalent/congruent.
We can use this information to set up an equation:

Add 3 to both sides:

Subtract 5x from both sides:

Divide both sides by 2

Answer:
Step-by-step explanation:19 and 31
Answer:
15 + x
Step-by-step explanation:
4t+ 14= 6t/5+ 7
⇒ 4t+ 14= 6/5t+ 7
⇒ 4t -6/5t= 7 -14
⇒ (4 -6/5)t= -7 (distributive property)
⇒ 14/5t= -7
⇒ t= -7/ (14/5)
⇒ t= -5/2
⇒ t= -2.5
Final answer: t= -2.5~
