Tisha and her academic team are working to go to state finals. They must have a certain number of points, T, to advance. They have had three local matches, b.
and d, and will attend a district match District match points count for four times the number of points than local matches do Choose the equation that would help
Tisha find how many points they need to earn in the district match, a, to advance.
a=1-b-cd
a=T-b-c-d
a-T+b+c+d
a = 4(T-D-C-d)
Pls answer ASAP

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
