6 0

Answer: x = 4.6

Step-by-step explanation:

From the diagram opposite is 4

Adjacent is x

@ = 41 degrees.

Solve from SOH CAH TOA

From here the one that has opposite and adjacent is TOA which is;

[email protected] = opposite/ adjacent

[email protected] = 4/x

x = 4/[email protected]

x = 4/tan 41

x = 4/0.869

x = 4.6

A triangle with one obtuse angle must also have two acute angles.a. trueb. false

stiks02 [169]

(a) True

Because the sum of the angles in a triangle is 180°

Obtuse angle = angle greater than 90°.

180° - Obtuse angle = less than 90°

So there cannot be another obtuse angles, therefore both the other angles will be acute.

If a^2 and b are directly proportional, and a=2 when b=9, then what is b when a=6?

Alisiya [41]

Answer:

b = 81

Step-by-step explanation:

given a² and b are directly proportional then the equation relating them is

a² = kb ← k is the constant of proportionality

to find k use the condition a = 2 when b = 9 , then

2² = 9k

4 = 9k ( divide both sides by 9 )

$\frac{4}{9}$ = k

a² = $\frac{4}{9}$ b ← equation of proportion

when a = 6 , then

6² = $\frac{4}{9}$ b

36 = $\frac{4}{9}$ b ( multiply both sides by 9 to clear the fraction )

324 = 4b ( divide both sides by 4 )

81 = b
