In the given figure we have two similar triangles:
a) Triangle ABC
b) Triangle ADE
Two sides of triangle ABC are 2 and x
The two corresponding sides of triangle ADE are (2+1)=3 and 1
The ratio of corresponding sides of similar triangles is always equal, so we can write:
Therefore, the measure of x will be 2/3
Answer:
The answer to your question is 9 cm
Step-by-step explanation:
Data
slant height = 15 cm
height = 12 cm
radius = ?
Process
To solve this problem, use the Pythagorean theorem. The slant height is the hypotenuse, the height is the long leg and the radius is the short leg.
c² = a² + b²
slant height² = height² + radius²
-Solve for radius
radius² = slant height² - height²
-Substitution
radius² = 15² - 12²
-Simplification
radius² = 225 - 144
radius² = 81
-Result
radius = 9 cm
<h2>♪Answer : </h2>
»f(x) = 7x² - 3x + 7
»f(2) = 7(2)² - 3(2) + 7
»f(2) = 7(4) - 6 + 7
»f(2) = 28 - 6 + 7
»f(2) = 29
»f(-1) = 7(-1)² - 3(-1) + 7
»f(-1) = 7(1) + 3 + 7
»f(-1) = 7 + 3 + 7
»f(-1) = 17
»f(0) = 7(0)² - 3(0) + 7
»f(0) = 7(0) - 0 + 7
»f(0) = 0 - 0 + 7
»f(0) = 7
so, f(2) + f(-1) + f(0) is
Answer:
CD = 9
Step-by-step explanation:
ΔADE is similar to ΔBCD
<u><em>Such that:</em></u>
AD is similar to CD
BD is similar to ED
AE is similar to BC
<u><em>Taking the proportion of their sides to find the unknown sides CD</em></u>
=> 
<em>Cross Multiplying</em>
=> 2(CD) = 3*6
=> CD = 18/2
=> CD = 9
