Step-by-step explanation:
That big triangle is made up of 2 congruent 30-60-90 triangles with each base measuring 4.5. You could use the tangent ratio to get tan60 = x / 4.5. Multiply both sides by 4.5 to get 4.5 tan60 = x. Do that on your calculator in degree mode to get that x = 7.79 or 7.8
Answer:
Step-by-step explanation:
Given that,
DE bisects OF, then OB is equal to BF,
So, OB is ½r
Also, DB is equal to BE, so BE = DB = 6 in
So, applying Pythagoras theorem to triangle OBE
OB² + BE² = OE²
(½r)² + 6² = r²
¼r² + 36 = r²
Multiply through by 4
r² + 144 = 4r²
144 = 4r² - r²
144 = 3r²
r² = 144 / 3
r² = 48
r = √48
r = √16×3
r = 4√3 inches
r = 6.93 inches.
So, the radius of the circle is 4√3 inches
The given system is
To solve this, we multiply the first equation by 2, then we sum equations.
Then, we divide the equation by 8.
Now, we use this value to find <em>y</em>.
<h2>Therefore, the solution to the system is (10, 0).</h2>
