What is the value of y? 2y y+10 50 all in degrees and in different angles of a triangle

The value of y = 40

Step-by-step explanation:

Measure of one angle of the triangle is given to be 2y

Measure of second angle of the triangle is given to be y + 10

Measure of the third angle of the triangle is given to be 50

Now, By using the angles sum property of a triangle, We have :

Sum of all the three angles of a triangle is always supplementary

⇒ ∠1 + ∠2 + ∠3 = 180°

⇒ 2y° + (y + 10)° + 50 = 180°

⇒ 3y + 10 + 50 = 180°

⇒ 3y = 120

⇒ y = 40

Hence, The value of y = 40

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
