Answer:
40°, 60° and 80°
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.
180° ÷ 9 = 20° ← value of 1 part of the ratio , then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The angles in the triangle are 40°, 60°, 80°
Answer:
b = 230 degrees a= 25 degrees
Step-by-step explanation:
d and e are right angles (90 degrees) because when tangent meets radius at circumference a right angle is formed.
c= 180 - 65 - 90 = 25 degrees because angles in a triangle add up to 180
both triangles are congruent as they share the middle line, they have tangents that meet radi(which are equal), and both have right angles. this means that all angles are same in the triangles so a =c =25 and f=65.
65+65=130
360-130 = 230
because angles around a point add up to 360.
b=230
Answer:
answer: $225
Step-by-step explanation:
500 dollars
45% off
you have to change the r5 into a decimal
(always us the discout go divide by 100)
45/100
.45
$500×.45=$225
The answer I believe is c
