Answer:

\theta=54.2^\circ

Step-by-step explanation:

<u>Right Triangles</u>

The ratios of the sides of a right triangle are called trigonometric ratios.  Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}

The opposite side is 25 and the adjacent side is 18, thus:

\displaystyle \tan\theta=\frac{25}{18}=1.389

The angle is calculated by using the inverse tangent function:

\theta=\arctan 1.389

\boxed{\theta=54.2^\circ}

MaRussiya [10]

Answer:

e) , f)

Step-by-step explanation:

42+15= 57

If the available options are:

a) 5(8+2)+5(3)=(5x10)+15=50+15=65

b) (3 x 14) + (3 x 5)= 42+15=57

c) (3 x 39) + (3 x 5)=117+15=132

d) 3(39 + 12)=3x51=153

e) 3(14 x 5)=3x70=210

f) 3(14 + 5)=3x19=57

Nuetrik [128]

Answer:

given chord AB=chord CD

L and M are the mid-points of two equal chords AB and CD of a circle

we have

(Equal chords are equidistant from the centre)

In ∆ OLM

OL = OM

<OLM= <OMLbase angles

opposite to equal sides of a A

But <OLA = <OMC(Each = 90°being perpendicular )

On adding

<OLM+<OLA = <OML+<OMC

=<ALM = <CML
