Answer:

55 degrees

Step-by-step explanation:

Hello There!

If you didn't know the measure of all of the angles in a triangle have a sum of 180

So to find a missing angle we subtract the two given angles from 180

We are given that one angle = 35 degrees

and another angle is a right angle

(a right angle measure 90 degrees)

Given this information we can find the missing angle of I

angle I = 180 - 90 - 35

180 - 90 - 35 = 55

so we can conclude that the measure of angle I is 55 degrees

Answer:

m < A = 60º

m < B = 30º

Step-by-step explanation:

The given sides on this triangle are: 6, $6\sqrt{3}$ , and 12

Any triangle with the angles of 30º - 60º - 90º always has side lengths in this proportion:

x, $x\sqrt{3}$ , 2x

We can line this up with the given sides. If x is 6, then 2x would be 12.

x : $x\sqrt{3}$ : 2x = 6 : $6\sqrt{3}$ : 12

Angle B is across from 6, the shortest side. That also means that it corresponds to x, or the smallest angle in the proportion, 30º.

m < B = 30º

Solving for < A:

Method 1) Sum of Angles in a Triangle

Since we already know that one angle is right and therefore 90º and m < B is 30º, we can subtract these from the total sum of angle measures in a triangle to get the last angle, < A.

180º - 90º - 30º = 60º

m < A = 60º

Method 2) Using the second part of the proportion

Since m < A is across from the second largest side, we know that it is equal to $x\sqrt{3}$ ( $6\sqrt{3}$ in this question) or 60º in the angle proportion.

This means that m < A = 60º

Let me know if you have any questions!

Step-by-step explanation:

Given

The linear equation is $5x+3y-9=0$

The other linear equation parallel to the given line can be represented by

$5x+3y+c=0$

Here, c can take any value . for example c=1, line becomes

$\Rightarrow 5x+3y+1=0$

Question 2. I have another question on my feed. Please help me solve!!!!

Maru [420]

Answer:

A' (11, 4), B' (-10, -6), C' (7, -9)

Step-by-step explanation:

Since you are reflecting over the y-axis, you take the opposite of the x value. So if the x is positive, make it negative. If the x is negative, make it positive. The y coordinate stays the same.

1044 fans join a club in the first month after the first month nine new members are allowed to join each month how many members

laiz [17]

Answer:

Total number of members in month 34 is 1341 members.

Step-by-step explanation:

We have given,

Number of fans join a club in first month = 1044

And after the first month nine new members are allowed to join each month.

After first month , Let the number of club members in x months will be given as:

Number of members = 1044 + 9x

We need to find number of members in month 34.

So for first month we already had 1044 members, that mean for remaining 33 months we need to calculate members.

i.e total number of members in month 34 = 1044 + (33×9 ) , {Since x = 33 here}

OR total number of members in month 34 = 1044 + 297 = 1341 members
