Answer:

90 degrees because A is an acute angle so x equals 45 degrees and so I multiply that by 2

So the right angle is equal to 90° and the rest is unknown.

using the triangle sim theorem, which states that all interior angles are equal to 180°.

so it would be x+2x+90°=180°.

then you would need to simply which is 3x+90°=180°

subtract 90° from both sides and get 3x=90°

and then divide both sides by 3 which is 30°

then you would need to find the angle of B which is 2x so you would need to substitute 30° for x which is 60°

the answer is 60°

What is the bisector of RS

Inessa05 [86]

Step-by-step explanation: A line, ray, or line segment (referred to as segment) that is perpendicular to a given segment at its midpoint is called a perpendicular bisector. ... In the diagram above, RS is the perpendicular bisector of PQ, since RS is perpendicular to PQ and PS≅QS. Additionally, since PS≅QS, point S is the midpoint of PQ.

Which system can be used to represent, x the number of tetra fish, and y, the number of goldfish, he purchased?

Fed [463]

The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following:

X = no of tetra fish
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.

X = 2Y.

Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.

In triangle ABC, the size of angle B is 4 times the size of angle A, and the size of angle C is 6°

amid [387]

Answer:

<A = 18.6 Degree

<B =74.4 Degree

<C = 87 Degree

Step-by-step explanation:

Sum of all the angles of triangle is 180

as given ,

<A = ?

<B = 4<A

<C = 5 <A - 6

As per rule ,

<A + <B +<C = 180

<A + 4 <A + 5<A - 6 = 180

10 <A - 6 = 180

10 <A = 180 + 6

<A = 186 / 10

<A = 18.6 Degree

Hence ,

< B = 4 X (18.6)

< B = 74.4 Degree

and

<C = 5 (18.6) - 6

<C = 87 Degree

PROOF

<A + <B + <C = 180

18.6 + 74.4 + 87 = 180

180 = 180

Brainiest to whoever right

Anna35 [415]

Answer:

since M lies between point A and B , we came to know that,

M(4,6) =(x,y)

A(-2,-1)=(x1 ,y1)

B( _, _ )=(x2,y2)

Now using mid point formula,

x=x1×x2÷2 y=y1+y2÷2

so, point B is (10,13)
