Part a: The value of x is 33°
Part b: The measure of each base angle is 69°
Explanation:
It is given that the vertex angle of an isosceles triangle measures 42°.
The base angle in the triangle has a measure of 
Part a: To determine the value of x
Since, in an isosceles triangle the base angles are always equal.
Thus, the three angles in an isosceles triangle add up to 180°
Hence, we have,
Thus, the value of x is 33°
Part b: To find the measure of each base angle.
Base angle = 
Substituting , we get,
Thus, the measure of each base angle is 69°
When you GRAPH an equation or inequality you plot all of the points that satisfy it.
Answer:
The fence will still be five feet high because the lengthening of the tree occurs at the apical meristem
Step-by-step explanation:
This is a simple and quick question to solve
years later after the tree is now thirty feet high, The barbed wire has been initially stapled at a height of five feet.
However a tree increases from its apical meristem therefore the barbed wire fence will still remain at that same height of five feet high.
Answer: the answer is D
Step-by-step explanation:
Answer:
168 meters squared
Step-by-step explanation:
The area of the triangle is A= 1/2 b*h. Here this area is 21 meters squared. The sides of the triangle have been multiplied by 4. This means, if the base was b, it is now 4b. This also means, if the height was h, it is now 4h. So the area is A= 1/2 4b*4h = 1/2 (16bh) = 8bh.
So the area of the larger triangle will be 8 times bigger.
21*8 = 168
