If angle TIK is congruent to angle TOK and < 1 = (5x + 8), < I = 92, and < O is 50. What is the measure of <1? Expla

Temka [501]

Answer: <1= 38 and x= 6

Step-by-step explanation: the sum of the angles of a triangle are equal to 180 degrees. Subtract 92 and 50 from 180 to get your answer.

Help me with the problem please!!

Step-by-step explanation:

Scale factor red to blue meaning 42 to 7

42÷7=6

Scale factor is 6

Perimeter of the blue quadrilateral = ?

If perimeter of red = 204

Then we use this following proportion

$204 \div 42 = x \div 7$

$\frac{204}{42} = \frac{x}{7}$

Then we cross multiply

42x=7×204

42x=1428

x=34

Area of the blue quadrilateral = ?

If area of the red quadrilateral = 2880

Then we use the following proportion

$2880 \div 42 = x \div 7$

$\frac{2880}{42} = \frac{x}{7}$

Then we cross multiply

42x=2880×7

42x=20160

x=480

Two vehicles are driving along a straight roadway at a constant speed. At a certain point in time, a car is 1.2 miles away from

Maurinko [17]

Answer:

The expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;

1.2 = 65 × t

Where t = 1.2/65 = 0.0185 h = 66.46 seconds

Step-by-step explanation:

The parameters given are;

Distance, d between car and landmark = 1.2 miles

Speed of car = 65 miles/hr

Distance between truck and landmark = 0.7 miles

Speed of car = 55 miles/hr

The expression for the total distance between the car and the landmark as a function of time t is given as follows;

Distance, d = Speed, v × Time, t

Therefore, the expression for the total distance between the car and the landmark in terms of the number of hours spent driving is given as follows;

1.2 = 65 × t

Where t = 1.2/65 = 0.0185 h = 66.46 seconds.
