Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
Answer:
ΔDEC/ΔRST is 13/3 it is c
Step-by-step explanation:
ΔRST/ΔDEC = 3/13 so the inverse is 13/3
Answer:
Step-by-step explanation:
We have to find the quotient of the following division, 
.
Now,
= ![- \frac{3}{4} p^{[- 4 - (- 12)]} q^{[-6 - (- 3)]}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B3%7D%7B4%7D%20p%5E%7B%5B-%204%20-%20%28-%2012%29%5D%7D%20q%5E%7B%5B-6%20-%20%28-%203%29%5D%7D)
{Since all the terms in the expression are in product form, so we can treat them separately}
{Since we know the property of exponent as 
}
= 
= (Answer)
{Since we know, 
}
Tan(x)= 33/105
x = arctan(33/105)
x = 17.44718842 degrees.
