Find the missing side. Round to the nearest tenth.

Mathematics
1 answer:
Firdavs [7]3 years ago

Answer: <em>23.7</em>

Step-by-step explanation:

<em>Let's calculate the acute angle at the base of the triangle:</em>

<em>180° - 90° - 40° = 50°</em>

<em>Find side x:</em>

\dfrac{sin \: 90^{o} }{31} =\dfrac{sin \: 50^{o} }{x}\\\\sin \: 90^{o} \cdot x=sin \: 50^{o} \cdot 31\\\\sin \: 90^{o} =1\\sin \: 50^{o} \approx 0.766\\1 \cdot x =0.766 \cdot 31\\x=23.746\\23.746 \approx 23.7

Identify the height of a triangle in which b=(x−2) m and A=(x2−4) m2. A) h = (2x + 4) m B) h = (2x + 2) m C) h = (x + 2) m D) h
hjlf

Answer:we know that

area of triangle=b*h/2

b=(x-2) m

Area=(x²-4) m²

h=?

(x²-4)=(x+2)*h/2

but remember that

(x²-4)=(x+2)*(x-2)

so

subsititute

(x+2)*(x-2)=(x+2)*h/2

(x-2)=h/2

h=2*(x-2)

the answer is

the height of a triangle is 2*(x-2)

Comparing Functions: Mastery Test
Brums [2.3K]

Answer:

Table 3 has a greater y intercept

Step-by-step explanation:

See attachment (1) & (2) for graph and tables

First, we have to determine the y intercept of the graph

The y intercept of any graph or table is the corresponding value of a point where x = 0

In the attached graph.

x = 0 when y = 4

So:

y\ intercept = 4

Next, we determine the y intercept of each table.

Recall that: The y intercept of any graph or table is the corresponding value of a point where x = 0

For table 1:

y\ intercept = 3

For table 2:

y\ intercept = 2

For table 3:

y\ intercept = 5

By comparison, the y intercepts of tables (1) & (2) are less than the y intercept of the graph because: 3 and 2 are less than 4

However, the y intercept of table 3 is greater than the y intercept of the graph because 5 is greater than 4.

<em>Hence, table 3 has a greater y intercept</em>
