Solve for angle..........

Mathematics
1 answer:
Hatshy [7]3 years ago
7 0

Answer:

57

Step-by-step explanation:

An angle formed by a tangent and secant is equal to half the difference of its intercepted arcs. ( major arc minus minor arc to be more specific. )

∠B is the angle formed by a tangent and secant

Arc CA is its intercepted arc ( minor arc to be more specific )

Arc DA is also its intercepted arc ( major arc to be more specific )

Hence, ∠B = \frac{1}{2} ( Arc DA - Arc CA )

If arc CA = 51 and Arc DA = 165

Then ∠B =

\frac{1}{2} (165-51)\\165 - 51=114\\\frac{1}{2} (114)=57

Hence, ∠B = 57

• Less than (<),

• Equal to(=),

• Not equal to,

• Greater than or equal to,

The area of a rectangle is found using the formula A=lw, where l is the length of the rectangle and w is the width. Multiply eac
charle [14.2K]

Answer:

A(x) = 3x² + 43x + 14

Step-by-step explanation:

Area of a rectangle = length × width

length = x + 14

width = 3x + 1

Area of a rectangle = length × width

= (x + 14)(3x + 1)

= 3x² + x + 42x + 14

= 3x² + 43x + 14

express the area of each rectangle as a single polynomial in terms of x.

A(x) = 3x² + 43x + 14
