in a triangle TRY measure angle R is 3 times measure angle T and measure angle Y is 15 more than measure angle T find the measur
r-ruslan [8.4K]

Answer:

Angle R is 99 degree

Angle Y=48 degrees

Angle T is 33 degrees

Step-by-step explanation:

Let angle T be x

Angle R will be 3x

Angle Y will be x+15

Total=x+3x+x+15=5x+15

5x+15=180

5x=165

x=165/5=33

Therefore, angle T is 33 degrees, angle Y=15+33=48 degrees and angle R=33*3=99 degrees

Solve for x: two thirds(x − 2) = 4x.
Sveta_85 [38]

Answer:

x =  - 0.4

Step-by-step explanation:

\frac{2}{3} (x - 2) = 4x

Expand with the distributive rule:

\frac{2}{3} x -  \frac{2}{3}  \times 2 = 4x

\frac{2}{3} x -  \frac{4}{3}  = 4x

Add 4/3 to both sides:

\frac{2}{3} x = 4x +  \frac{4}{3}

Subtract 4x from both sides

- \frac{10}{3} x =  \frac{4}{3}

- 10x = 4

x =  - 0.4

Good evening! Can someone please answer this, ill give you brainliest and your earning 50 points. Would be very appreciated.
Tanzania [10]

Tyler concludes that 5x² will always have a larger output for the same value of x.

<u>Look at the graph below and the table given</u>

Take a random value: x = 0

  • When 5x², y = 0
  • When 2^x, y = 1

Here, 1 > 0, making 2^x > 5x²

Hence, 2^x is greater than 5x² at this point. making Tyler's point not applicable.

Disagree with Tyler's point.
