Find the degree triangle

Mathematics
1 answer:
coldgirl [10]2 years ago
6 0

Answer:

A) 7

Step-by-step explanation:

Because the triangles are congruent to each other, then their corresponding angles are also congruent to each other. Thus, angles Z and V are congruent to each other:

\angle Z=\angle V\\\\40^\circ=(5n+5)^\circ\\\\35=5n\\\\7=n

Therefore, your answer is A.

What is the first term in the sequence for which d = -2 and a7 = 3?
AnnZ [28]

Answer:

Final answer is c. 15

Step-by-step explanation:

We need to find about what is the first term in the sequence for which d = -2 and a7 = 3

We will use nth term formula of arithmetic sequence.

a_n=a+\left(n-1\right)d

we have been given a7 that means 7th term is 3

so plug n=7, d=-2 and a_n=3 into above formula

3=a+\left(7-1\right)(-2)

3=a+6(-2)

3=a-12

15=a

Hence final answer is c. 15

Mai is filling her fish tank. Water flows into the tank at a constant rate. Complete the table and answer the question below.
kvasek [131]

Answer:

r = 1.6

Step-by-step explanation:

Given

x   -----   y

0.5. --- 0.8

1. --- 1.6

3.--- 4.8

25. --- 40

Required

Determine the constant of proportionality

This can be calculated using the following formula:

y = rx ; Where r is the constant of proportionality;

Solve for r

r = \frac{y}{x}

When x = 0.5; y = 0.8

r = \frac{0.8}{0.5}

r = 1.6

When x =  1; y =1.6

r = \frac{1.6}{1}

r = 1.6

When x =  3; y = 4.8

r = \frac{4.8}{3}

r = 1.6

When x =  25; y = 40

r = \frac{40}{25}

r = 1.6

Notice that the value of r is constant throughout;

Hence:

r = 1.6

Could these triangles be congruent?
Mama L [17]

Answer:

yes, if AB ≅ DE

Step-by-step explanation:

Triangles are said to be congruent if they have the same sides and the same angles.

The following measures are used to determine if triangles are congruent:

1) Angle-side-angle: If two angles and a side of a triangle is equal to two angles and corresponding side of another triangle, then they are congruent.

2) Side-side-side: If all three sides of a triangle is equal to three sides of another triangle, then the two triangles are congruent.

3) Side angle side: If two sides and an included angle of a triangle is equal to the two sides and corresponding angle of another triangle, then they are congruent.

4) Hypotenuse - leg: If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.

From the triangles  DEF and ABC, already, they already have one equal triangle that is ∠F = ∠B and an equal side i.e DF = AC.

To satisfy congruence, two sides and an angle have to be equal, therefore if AB = DE then the two triangles would be congruent
