Please help me solve for x

Mathematics
1 answer:
ratelena [41]3 years ago

Hello from MrBillDoesMath!

Answer:

sqrt(6)

Discussion:

The triangle, while not indicated, appears to be a right triangle (i.e. has a 90 degree angle). If so, from the Pythagorean theorem,

x^2 + 3^2 =   ( sqrt(15) ) ^ 2  =>

x^2 + 9 = 15                          =>  ( subtract 9 from both sides)

x^2   = 15 - 9 = 6                  =>  (take the square root of both sides)

x= sqrt(6)



Regards,  

MrB

What is the value of x?
KatRina [158]

Answer:

X = 98°

Step-by-step explanation:

53° + 45° + FGH = 180° ( Interior angle property)

FGH = 180° - 98 °

FGH = 82°

Now,

By x would be solved through linear pair.

x° + 82° = 180° ( linear pair)

x° = 180° - 82°

x = 98°

hope it helps!

May someone please help me on which to graph?
olga_2 [115]

Answer:

Option (4)

Step-by-step explanation:

Proportional relationship means,

y ∝ x

y = kx

k=\frac{y}{x}

Here, k = proportionality constant

Therefore, if the graph of a line passes through the origin (0, 0) table will represent the proportional relationship.

From table 1,

For a point (1, 2)

k=\frac{2}{1}=2

For another point (3, 2)

k=\frac{3}{2}=1.5

In both the cases 'k' is not same of constant.

Therefore, table (1) is not proportional.

For table (2),

Line passes through (2, 0).

That means there is a x-intercept → (2, 0)

Therefore, table doesn't represent a proportional relationship.

For table (3),

Line passes through a point (0, 1)

It means given line has a y-intercept → y = 1

Therefore, table doesn't represent a proportional relationship.

For table (4),

Line of this table passes through two points (1, 3) and (2, 6)

k=\frac{3}{1}=3

k=\frac{6}{2}=3

Therefore, proportionality constant for the given table is 3.

Now we can graph table (4).
