Answer:

Step-by-step explanation:

148.5 - 144 = 4.5

$\frac{Difference}{Initial Amount}$ × 100

$\frac{4.5}{148.5}$ × 100 = 3.03 ≈ 3%

Answer:

Original height = 144 cm

Increase height = 148.5 cm

Change in height = 148.5 - 144 = 4.5 cm

Percentage change = change/original ×100

= (4.5 / 148.5) × 100

= 3.03%

The height increased by 3.03%.

Help me plz i dont understand how t=40

timama [110]

Answer:

t=40

Step-by-step explanation:

The sum of all angles in a triangle will always equal 180°. This means that:

(2t-42)+(4t-49)+(2t-49) = 180°

Let's solve this equation!

(2t-42)+(4t-49)+(2t-49) = 180

First we simplify what's on the left side:

2t-42+4t-49+2t-49 = 180

2t+4t+2t-42-49-49 = 180

8t-140 = 180

*Add 140 to both sides

8t = 180+140

8t = 320

Divide both sides by 8 to know what t means:

t = 320/8

t = 40
