Triangle angle - sum theorem what is the value of y?

dangina [55]

Answer:

y = 5

Step-by-step explanation:

All angle measures in a triangle add up to 180°.

This means that 63 + 82 + 7y = 180

Solving for Y:

Step 1: Combine like terms.

$(7y) + (63+82)=180$
$7y + 145 = 180$

Step 2: Subtract 145 from both sides.

$7y + 145 - 145 = 180 - 145$
$7y = 35$

Step 3: Divide both sides by 7.

$\frac{7y}{7} = \frac{35}{7}$
$y = 5$

Step 4: Check if solution is correct.

$7(5) + 63 + 82 = 180$
$35 + 63 + 82 = 180$
$98 + 82 = 180$
$180 = 180$

Therefore, y = 5.

The driving distance between Manchester and london is 195 miles. Fairs intends to travel from Manchester to London by coach. The

Nadya [2.5K]

Answer:

7:24 pm

Time taken will be longer

Step-by-step explanation:

Given that:

Distance between Manchester and London = 195 miles

Departure time = 3.30 pm

Average speed of Coach = 50 mph

Arrival time in London :

Time taken = distance / speed

Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes

= 3:30 pm + 3 hours 54 minutes = 7:24 pm

If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm

Help solving this I’m don’t understand

ladessa [460]

AB is a chord that passes through the center O, which means the central angles BOC and AOC are supplementary. So

$m\angle BOC+m\angle AOC=180^\circ\implies m\angle AOC=180^\circ-55^\circ=125^\circ$

Central angles and the arcs they subtend have the same measure, so that

$m\widehat{AC}=m\angle AOC=125^\circ$

$m\widehat{CBA}=m\widehat{BC}+m\widehat{AB}=m\angle BOC+m\angle AOB=55^\circ+180^\circ=235^\circ$
