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°.
Find the reciprocal of 3/5 (by flipping the fraction)
5/3
Multiply 5/3 by 3/4
3/4(5/3)= 15/12= 1 1/4
Martina can walk 1 1/4 miles in one hour.
Hope this helps!
Write and solve an equation of ratios:
vinegar 0.25 x
------------ = --------- = -----------
dressing 1.00 2 cups
Cross multiply. We get 0.5=x. Sue needs to use 1/2 cup of vinegar and 1 1/2 cups of the other ingredient(s).
Answer:
The equation of the line is x = 2
Step-by-step explanation:
* It is a coordinate geometry problem.
We need to find the equation of a line with undefined slope.
* The slope is undefined
The line passing through point (2 , 5)
* The rule to find the slope is 
The slope is undefined if 
That means the line passing through points have same x-coordinate
That means the line is vertical
* ∵ The line passing through point (2 , 5)
∵ The slope of the line is undefined
∴ All the points on the line have x-coordinate = 2
∴ The equation of the line is ⇒ x = 2
* The answer is x=2
