Answer:
m<A = 84
AC = 9
Step-by-step explanation:
We can find the measure of Angle A by using the sum of interior angles of a triangle theorem.
48+48+A=180
96+A=180
A=84
We can then use the isosceles triangle similarity theorem and reason that since this is an isosceles triangle and one of the side lengths (AB) is 9, the other (AC) would also be 9.
Answer:
Step-by-step explanation:
Eqn. 1 ----> 4y = x
Eqn. 2 ----> 5x-10y = -50
(Simplifying eqn.2 further)
(Substituting the value of x from eqn. 1)
Now, substituting the value of y in eqn. 1 ,
Answer:
y= 29
step by step explanation:
y= 6 x 2 + 17
y= 12+17
y= 29
Answer:
B. 271 square units
Step-by-step explanation:
The area is the sum of 3 rectangles areas
step 1 12 * 19 = 228
step 2 3 * 3 = 9
step 3 2 * 17 = 34
Now, we add all the answers we got to get the area.
= 228 + 34 + 9 = 271 square units
Answer:
75 degrees
Step-by-step explanation: the 15 degree angle is adjacent to angle fgd so its 15 and then all of the other angles add up to 90 degrees then you subtract 15 from 90 and get 75. Im not very good at explaining it don't know if im using the right terms but I know how to do it for sure.
