Answer:
The value of x is 104
Step-by-step explanation:
we are given 52 we know that 52 is within an isosceles triangle.
which means 2 sides are the same which tells us that the two angles touching the unique side will have the same measure
we also know that a triangle adds up to 180 so 52 + 52 gives us 104 meaning the last angle will be 180 - 104 which is 76
now we have completed the first triangle if
if we look at corner c we know that it's a right angle
we know that right angles are a total of 90 degrees we know that the right angle is split into two complementary angles one of them is 52 which we figured from the first part so
90 - 52 would give us 38 now we know that in triangle CDE one of the measures is 38 at the c corner and another is 90 at the E corner
once again we do 90 + 38 = 128 and subtract that from 180 giving us 52.
Now we know the measures of triangle ADC and CDE
We also know that triangle EDB is a congruent mirror reflection of CDE
So by now we have the measures of 3 triangles CDE ADC AND EDB
we also know that angle F/x is equvilant to the total of both of angle D
so we just add 52 + 52 giving us the measure of the whole angle d combined which we know is eqivilant to angle f
So after all that we know that the value of x is 104 degrees.
Hope this helps its a long explanation but please take ur time to understand and read through it :)
Answer:
6ab
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)
Answer:
540
Step-by-step explanation:
-10 * -6 = 60
60 * 9 = 540
When you multiply two negatives, the negative sign cancels out, and the number becomes positive.
