A line = 180°
180 - m∠2 = m∠5
180 - 102 = m∠5
180 - 102 = 78
78° = m∠5
Answer: It is 4/5 x 45
Step-by-step explanation: Hope i helped please mark brainliest!
I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30
therefore, 4/5 x 45 is greater!
also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.
Answer:
4.72 in.
Step-by-step explanation:
BC = 3.1 in.
CD = 7.2 in.
Altitude of right triangle altitude is given as 
, where:
h = altitude
x = 3.1 in.
y = 7.2 in.
Plug in the values into the formula
(nearest hundred)
Since they are similar triangles, they are just enlarged versions of each other. This means that the left-most angle of triangle XYZ is also 35°.
Angles in a triangle add up to 180°, so we can find the missing angle by subtracting the two known angles from 180.
180 - 70 - 35 = 75
The right-most angle of triangle XYZ would be 75°.
Hope this helps!
PEMDAS
3 ( x - 7 ) = 9 ( 4x + 5 )
3x - 21 = 36x + 45
-36
-33x - 21 = 45
+21
-33x = 66
------ ------
-33 -33
x = -2
Your answer should be -2
I hope this helps!
