Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.
Answer: y=-2x-1
Step-by-step explanation:
First let's find the slope by using the formula 

The equation for slope intercept form is y=mx+b where m is the slope and b is the y-intercept
The y-intercept is -1 giving us the equation
y=-2x-1
Answer:
64 oz= 4 lbs
5 gal= 20 qt
660 yds = 0.375 miles
¼ miles = 440 yds
24 oz = 3 cups
4 c = 32 oz
24 ft = 8yds
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
fill in x and y

then simplify
this is true because 2 is less than or equal to 2
