35 + 25 + x = 85
60 + x = 85
x = 25cm
The third side is 25 cm
He went 90 miles, 180 minutes. explanation: there are 4 , 15 minute intervals in an hour. 4 x 15 is 30. so 30 miles an hour. you multiply 30 miles x 3 hours and get 90 miles. then there’s 60 minutes in an hour and 60 x 3 is 180.
Answer:
The value of DC is 66.34.
Step-by-step explanation:
The triangles ABC and DCA are right angled triangles.
The straight line AC is a bisector for angles C and A.
The measure of ∠C is 30°.
Then the measure of angles BCA and ACD will be 15° each.
The measure of angle DAB is 150°.
Then the measure of angles DAC and BAC will be 75° each.
Now consider the right angled triangle ABC.
The measure of side AC is:
Consider the right angled triangle DCA.
The angle DAC measure 75°.
Using the trigonometric identities compute the value of Perpendicular DC as follows:
Thus, the value of DC is 66.34.
A cylinder has 2 flat surfaces and has 0 edges and vertilies.
Answer:
x = 32, ∠A = 132
Step-by-step explanation:
A and B are equal. Set both equations equal to each other.
5x - 18 = 3x + 42
Add 18 to both sides and subtract 3x from both sides.
2x = 60
Divide both sides by 2.
x = 30
Now plug x back in to solve for angle A.
5(30) - 18 = 132
