This is an equilateral triangle because all the sides are the same length shown by the tic marks. This means that the angles are also all congruent. so...
S=T=R this also means that all angles are 60 degrees because all triangles angles added together are 180 degrees. so that means that you put all of the equations equal to 60. but if u are looking for x only here is the answer
7x+4=60
7x=56
x=8

Answer:

The value of x is equal to

x=8\°

Step-by-step explanation:

we know that

The equilateral triangle has three equal sides and three equal angles

The triangle of the figure is an equilateral triangle

The measure of the internal angle is equal to 60\°

so

Find the value of x

(7x+4)\°=60\°

Solve for x

7x=60\°-4\°

x=56\°/7

x=8\°

(3a2 + 2ab + 2b) + (5a2 − 3ab + 9)
ivann1987 [24]

Step-by-step explanation:

\tt{(3 {a}^{2}  + 2ab + 2b) + (5 {a}^{2}  - 3ab + 9})

~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :

⤑ \tt{3 {a}^{2}  + 2ab + 2b + 5 {a}^{2}  - 3ab + 9}

~Like terms are those which have the same base. Combine the like terms :

⤑ \tt{3 {a}^{2}  + 5 {a}^{2}  + 2ab - 3ab + 2b + 9}

⤑ \sf{8 {a}^{2}  - ab + 2b + 9}

\red{ \boxed{ \boxed{ \tt{ ⟿ Our \: final \: answer : 8 {a}^{2}  - ab + 2b + 9}}}}

Hope I helped ! ツ

Have a wonderful day / night ♡

Each of the performers at a circus convention is either a unicyclist, a mime or an aerial artist. The ratio of unicyclists to mi
Alexeev081 [22]

Answer:

14.52% are unicyclists

Step-by-step explanation:

First, we can use proportions to find the number of unicyclists at the convention. Since we know that the ratio of unicyclists to aerial artists is 9:11, and there are 88 aerial artists, we can set up the following equation:

\frac{9}{11}=\frac{x}{88}

If we cross multiply, we get that 11x = (88)(9). After we divide through by 11 to isolate x, we get that x = (8)(9) = 72

Second, we have to figure out the number of mimes at the convention to figure out the total number of people there. We know that the ratio of unicyclists to mimes is 3:14, and the number of unicyclists is 72. So, we can set up the following proportion:

\frac{3}{14}=\frac{72}{y}

If we cross multiply, we get that 3y = 1008, or y = 336 mimes

The total number of people at the convention is 336 mimes + 72 unicyclists + 88 unicyclists = 496. Now we have to figure out what percent of 496 is 72 (the number of unicyclists). If we let z = the percentage, we can simply set up an equation that says that 72 is z% of 496:

72=0.01z*496\\0.01z=0.14516\\z=14.52

This means that approximately 14.52% of the performers are unicyclists.

The sum of the square of a positive number and the square of 3 or more than the numbers is 17. What is the number
Crank

Answer:

 1

Step-by-step explanation:

Let x represent the number. The given relation is ...

 x² +(x+3)² = 17

 2x² +6x +9 = 17 . . . . simplify

 x² +3x -4 = 0 . . . . . . subtract 17 and divide by 2

 (x +4)(x -1) = 0 . . . . . factor

The solutions make these factors zero: -4 and +1. The positive solution is 1.

The number is 1.
