What is x=? I got part a but what does x=?
Oksi-84 [34.3K]

Answer:

I think x = 44°

Step-by-step explanation:

Finding the exterior angle:

180° - 45° = 135°

We know that x is multiplied by 3 (3x) so we divide 135 by 3.

135° / 3 = 45°

We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.

Trying a few possible answers:

43° × 3 = 129°

129° + 3° = 132°

That one wasn't quite right.

44° × 3 = 132°

132° + 3° = 135°

Please help urgent!!
USPshnik [31]

Answer:

Q M \cong R M \Rightarrow definition of midpoint

\overline{P M} \cong \overline{P M} \Rightarrow Reflexive property of congruence

\Delta P Q M \cong \Delta P R M \Rightarrow SSS congruence postulate

\angle Q \cong \angle R \Rightarrow CPCTC theorem

Step-by-step explanation:

Step 1: Since, M is the midpoint of the line segment QR.  

\overline{Q M} \cong \overline{R M} \Rightarrow  definition of midpoint

Step 2: The reflexive property of congruence states that a line segment or an angle or a shape is always equal to itself.  

\overline{P M} \cong \overline{P M} \Rightarrow Reflexive property of congruence.

Step 3: The SSS congruence postulate states that if three sides of a triangle are equal to three sides of another triangle, then the two triangles are congruent.

\Delta P Q M \cong \Delta P R M \Rightarrow  SSS congruence postulate

Step 4: CPCTC theorem states if two triangles are congruent then the sides and angles are also congruent.

\angle Q \cong \angle R \Rightarrow CPCTC theorem.

A turtle and a snail are 300 feet apart when they start moving towards each other. The turtle is moving at a speed of 5 feet per
Vladimir [108]
It will take 50 minutes for the turtle and snail to meet.
because they are all moving at feet per minute we can create a formula
total feet = (turtle feet per minute) + (snail feet per minute)
300 = 5m +1m
combine like terms
300 = 6m
divide both sides by 6 
50=m
