Find the size of unknown angles

Mathematics
1 answer:
Luden [163]3 years ago
4 0

Answer:

ok in this diagram we have two triangles the first triangle all angles are unknown the second triangle we have the values of two angles so we will start with the second triangle and as you know angles in a triangle add up to 180° so we will take 35 degrees + 30 degrees and name the unknown angle x is equals to 180 degrees so it will be 65 degrees + x is equals to 180° put the like terms together x will be equal to 180 degrees - 65 degrees it becomes a minus because when a plus crosses the equal sign it becomes - so x is equals to 115° and as you can see in the diagram 115° is vertically opposite z then you can extend the lines so as to understand the diagram better when you extend the lines you find that 35 degrees is equal to angle v so it will be 115 degrees + 35 degrees + x is equals to 180 degrees so 150° + x is equals to 180 degrees put the like times together x is equals to 180 degrees minus 150° x is equals to 30 degrees

A book club has 36 members. There are 24 boys and 12 girls in the club. What is the ratio of the number of boys in the club to t
Ivanshal [37]

Step-by-step explanation:

Ratios can be written as:

a to b

a:b

a/b

We want to find boys to girls, and there are 24 boys and 12 girls. So, we can write it as

24 to 12

24:12

24:2

All of these can be reduced, since both the numerator and denominator can be divided by 12.

Numerator: 24/12=2

Denominator: 12/12=1

2 to 1

2:1

2/1

HELLO PLEASE GIVE ME THE RIGHT ANSWER ASAP THANK YOU !
seropon [69]

\large\underline{\sf{Solution-}}

\textsf{Given expression;}\\

\rm{23 =  \frac{7}{9}(6x - 36) + 9 } \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 256)}{9}  + 9 \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 256 + 81)}{9}  \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 175)}{9}  \\

\rm{\longmapsto} \:  \frac{23}{1}  =  \frac{(42x - 175)}{9}  \\

\textsf{By doing cross multiplication, we get}\\

\rm{\longmapsto}23(9) = 1(42x - 175) \\

\rm{\longmapsto}207 =42x - 175\\

\rm{\longmapsto} \: 42x =  - 175 - 207 \\

\rm{\longmapsto} \: 42x =  - 379 \\

\rm \therefore \: x =  -  \frac{375}{42}  \\

\textsf{Hence, the value of x will be -375/42 respectively.}\\

Which line has a slope of -5?
il63 [147K]

A negative slope makes a line go down to the right.

The line C goes up to the right, so that is not it.

slope = -5 = rise/run = -5/1

For every 5 the y-coordinate goes down, the x-coordinate goes 1 to the right.

Only line B goes down 5 and right 1, so the answer is line B.

Answer: Line B
