In this figure, AB¯¯¯¯¯∥CD¯¯¯¯¯ and m∠4=85°.

Stolb23 [73]

AB∥CD and m∠4=85°.

<1 = 180° - 85°

<1 = 95°

Because AB∥CD so <5 = <1 = 95° (corresponding angles are equal)

Answer

<5 = 95°

Two hundred people attended the history museum exhibit on Monday. Twenty-five of the people who attended the exhibit were survey

galben [10]

Answer:

Step-by-step explanation:

Total number of people attending the history museum is 200

Surveyed people are 25

Out of the 25, 12 people said yes

Therefore; the fraction which said yes = 12/25

To find the total number of people expected to say yes out of those that attended the history museum;

Fraction of the sampled that said yes × total number of people that attended.

= 12/25 × 200

= 96

How do I do this? Help!

Hitman42 [59]

Notice the picture below

you have two triangles, and you have the opposite and adjacent sides

thus, recall your SOH CAH TOA $\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}$

anyhow.. the one that has only
the angle
the opposite
and the adjacent

is Ms Tangent, so lets ask her some

$\bf tan(29^o)=\cfrac{x}{y}\implies y\cdot tan(29^o)=x
\\\\\\
tan(25^o)=\cfrac{x}{100-y}\implies (100-y)tan(25^o)=x\\\\
-----------------------------\\\\
x=x\qquad thus\qquad y\cdot tan(29^o)=(100-y)tan(25^o)$

solve for "y"
