What do you mean?!? I don’t understand
We know that
[lateral area]=perimeter of the base*height
perimeter of the base=10+24+26-----> 60 cm
height=26 cm
[lateral area]=60*26-----> 1560 cm²
the answer is
the option A) 1560 cm²
Answer:
B. 10.
Step-by-step explanation:
This is the number of combinations of 3 from 5.
5C3 = 5! / 3! (5-3)!
= 5*4*3*2*1 / 3*2*1 * 2*1
= 5*4/2*1
= 10.
Triangle QST is an isosceles triangle. You can tell because two of the legs are congruent. Thus angle T is also an x-variable.
Add all of the degrees together, set them equal to 180 and solve for x.
x + x + 74 = 180
2x + 74 = 180
2x = 180 - 74
2x = 106
x = 53
This rules out options C and D.
Now we have to find angle PQS:
The measurements of triangle PQR are congruent to each other so 180 / 3 = 60 they are all 60 degrees.
Angles PQR, PQS, and SQT are in line with each other so they add up to 180.
60 + PQS + 74 = 180
134 + PQS = 180
PQS = 180 - 134
PQS = 46
Triangle PQS is another isosceles triangle. Thus, the two base angles are the same. We are going to add them together plus y and set it all equal to 180 to solve.
46 + 46 + y = 180
92 + y = 180
y = 180 - 92
y = 88
x = 53, y = 88. Your answer is option B
<h2>Greetings!</h2><h3>Firstly, the slope is found by rearranging the formula:</h3>
3y = 4x + 39
y = +
When x is 0, y = 0(x) + , so the y intercept is
<h3>Next, the slope is simply the number in front of the x, </h3>
So can be rearranged to , so the slope would be .
