The segments above the bisector are proportional to the corresponding segments below.

(4x +1)/5 = 15/3
4x +1 = 25
x = (25 -1)/4 = 6

The value of x is 6.

The measure of an angle is three more than twice its supplement. What is the measure of the angle?

Zinaida [17]

Answer: the angle is 1°+n×120°

1°, 121°, 241°

Step-by-step explanation:

Angles are taken modulo 360°, so 363° = 3°.

Angle plus supplement gives 180°.

Let a be angle, s be supplement of a.

So s = 180-a. Given a = 3 + 2s

a = 3 + 2(180 - a)

a = 3 + 360 - 2a = 363 - 2a

3a = 363° or 3° or 723°

a = 121° or 1° or 241°

a = 1°

s = 179°

2s = 358°

2s+3 = 361° = 1° (modulo 360)

a = 121°

s = 180-121 = 59°

2s = 118°

2s + 3 = 121°, as required.

a = 241°

s = 360+180-241 = 540-241 = 299

2s = 598

2s + 3 = 601 = 241 (modulo 360)

Priya has picked 1 3/4 cups of raspberries. She uses 1/5 cup of raspberries for a bottle of jam. How many bottles of jam can she

Scilla [17]

Answer:

$=8 \dfrac{3}{4} jams$

Step-by-step explanation:

Given that:

Priya has $1\dfrac{3}{4} \ cups \ of \ raspberries$

If she uses $\dfrac{1}{5} cups \ on \ jam$

∴

Then she will be able to make:

$=1\dfrac{3}{4} \div \dfrac{1}{5}$

$= \dfrac{7}{4} \times \dfrac{5}{1}$

$= \dfrac{35}{4}$

$=8 \dfrac{3}{4} jams$
