what is the missing angle measurements for the isosceles triangle it has a picture of a triangle and has 70°
bulgar [2K]
Well if they part that has 70 degrees is congruent to any other side it is 70 + 70 which equals 140 and 360 which is a complete circle minus 140 is 220  the missing angels are there fore 70 and 220   or if the angle isnt congruent then the other sides must be so what plus itself on top of adding 70 will get us 360. lets find out what 220 in half is   since 220 and 70 equals 360. 110 is 220 in half so the sides missing on this could be 110 110

<h3>What is probability?</h3>

probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

Given:

If a multiple choice test consists of 5 questions each with 4 possible answers of which only one is correct,

,To find  how many different ways can a student check off one answer to each question we have,

: 4^5 = 2^10

= 1024

Therefore, the different ways can a student check off one answer to each question is 1024.

Are the two statements equivalent the ratio of orange. to blue is 3 to 4 <br><br>please help
Anestetic [448]

Answer:

Although I'm not entirely sure of the question (sorry lol), any ratio that is 1.5:2 , 6:8 , 9:12 , 12:18 etc would be equivalent to 3 to 4.

Step-by-step explanation:

If you divide both 3 and 4 by 2 you'd wind up with 1.5 ( 3 ) and 2 ( 4 ). When multiplying, you'd get 3x2 = 6 and 4x2=8, 3x3 = 9 and 4x3 = 12 and so on.
