Answer:
a= 140 b=140 c= 40 d= 140
Step-by-step explanation:
a b and d are congruent to the given angle and d is supplimentary to c so 140 +40 = 180

Answer:
x = 45
Step-by-step explanation:
We see that the triangle is both a right-angled triangle and an isoceles triange. This means that the three angles are:
a 90
b = c
c = b
We also know that the maximun amount of degrees in a Euclidean triangle is 180 degrees, so
2x = 180 - 90
180 - 90 = 90
90 = 2x
90 / 2 = 45
So, x = 45
Answer:
12
explanation:
the ratio is 2:5 so we know that for every 5 green stickers, Emerson has 2 yellow stickers.
So, we know that 5 goes into 30 6 times so all you have to do is 6 x 2 = 12
We'll want to end this one with x ≥ another value.
So, subtract 5 from both sides.
x+5≥10
-5 -5
x≥5
So, x must be greater than or equal to 5.
