Answer:
y=X+3
Step-by-step explanation:
the y intercept is 3
from the graph we obtain two points
(7,6) (6,5)
6-5/7-6=1
y=Mx+c
y= x+3
Here is all my work along with some steps. Hope it helps.

Kindly check explanation
Step-by-step explanation:
xbar = 2.6
Sample size, n = 100
s = 0.4
Mean, μ = 4
The test statistic :
(xbar - μ) ÷ s/sqrt(n)
(2.6 - 4) ÷ 0.4/sqrt(25)
1.4 ÷ 0.08
= −17.5
Critical tvalue for 95% confidence interval :
df = n - 1 = 25 - 1 = 24
Tcritical at 0.05/2; df
Tcritical = ±2.064
Since, Tstatistic value does not fall within the Tcritical value ±2.064, we reject the Null
Using the p value from Tstatistic calculator :
P value at t = - 17.5 at 0.05 < 0.000001
Since p value is < 0.05, we reject H0.
Answer:
Let us make the last unknown interior angle be "b"
b+a+36=180
b=180-36-a
b=144-a
for the main triangle,
a+144-a+a-28=180
2a+116=180
2a=180-116
2a=64
a=32
so a=32
